A monitor is turned off and the computer hangs. Causes of monitor disconnection during the game. For owners of old monitors

At first glance it may seem that the monitor is a less important hardware component of the computer than, say, processor or hard disk. This is partly true, since the display, if it is external, it is easier to replace, but if it fails, and the processor, and the hard disk turn out to be useless, because the system management without an interface becomes impossible. And, I must say, the problems with the display the phenomenon is not already already and rare, and most often the users have to deal with its sudden disconnection.

Occupation may occur at any time, the monitor periodically goes out and it seems like without reason, although this, of course, is available. And, in general, the reasons can be a great set, so that problems have often arise with the diagnosis of this problem. For example, when the monitor is turned off, and the computer continues to work, it may indicate both a hardware malfunction and on the work of graphic drivers, and, unfortunately, with the first reason you have to deal with much more often.

Nevertheless, first still it is worth excluding the software component. If before that you deleted or updated the video card driver, it is quite possible that the new version of the video driver calls the problem. In this case, it is recommended by booting in secure mode, delete a problem driver and install a worker or roll back to the previous one. If the monitor is turned off during the game, the culprit can also be a driver, not cope with its tasks. This happens when launching "heavy", demanding hardware resources of the video card game. Here, on the contrary, it makes sense to update the drivers to the latest version or install software from a third-party developer, for example, NVIDIA.

What else causes a sudden disconnection of the monitor? Let's deal with.

System settings

First of all, consider the situation when it really does not matter any problems. A very common reason for which the monitor is turned off during computer operation is the operation of the Display Disconnection function after a certain time available in all popular versions of Windows. True, it is activated only if the user does not make any actions on the PC. If this is your case, open the settings of the current power scheme and see if you have time to configure the "Disable Display". If yes, select "Never" in the drop-down list.

Hardware problems

Often the monitor is spontaneously turned off due to hardware problems that can be very different. Banal situation - damage to the cable or connector. If the cable is old or exposed to strong external influences, it is likely that it has defects. Inspect it, make sure that there are no fuses and beggars, at the same time check the health of the connectors and adapters. To completely eliminate the problems with the cable, replace it with a new one.

Faulty monitor

It is not necessary to discard the problem with the malfunction of the monitor itself, however, in this case, it will most likely stay dark or go out after a few seconds after turning on the computer, although there are exceptions when the monitor screen periodically goes out for a couple of seconds. The first can serve as a sign of problems with illumination lamps, the second is to indicate the voltage inverter fault.

In order not to guess, what's the matter, disconnect the monitor from the system unit. If it is working, the message "No Signal" or "Cable is disabled" should appear on the screen, otherwise it will indicate a malfunction with the display itself. If possible, try connecting the monitor to another PC.

Fault video card

This is another reason why the monitor goes out during the computer. What to do in this case? As a rule, the video card is replaced, but before that, you still need to make sure that the problem is caused by it. Remove the video card, check it for a disconnected capacitors, traces of oxides, etc., make sure that the contacts are correct, and then insert into place. If you have a different computer at hand, test the video card on it.

Overheating of hardware components

Overheating of components, including a graphics card, does not always lead to a BSOD or a computer shutdown. Increased loads arising, for example, when starting particularly demanding games, may well cause the disconnection of individual components. If the monitor goes out during the game, and the systemist continues to work and the audio is also reproduced normally, the overheating is very even probable. The problem is solved by cleaning the system unit, installing a more efficient cooling system ,.

Unstable operation of the monitor power supply

It also happens that the monitor screen periodically goes out for 1-2 seconds, and then the image appears as anything happened. This may indicate a problem with a monitor power supply that cannot be coping with voltage drops on the network, as well as the poor condition of cable contacts. The less likely causes of such behavior are the malfunctions of the motherboard itself, the conflict of video cards (it is recommended to turn off one), problems with RAM (it is rare).

Incorrectly selected permission

The monitor turns off during the game or just work, sometimes the incorrectly selected permission is to blame. If, using third-party tools, set permission exceeding the capabilities of the monitor, it is very easy to turn off the latter, especially when you start games. An explicit sign of incorrectly selected resolution is the message "Outside range".

In this case, it will be necessary to boot in safe mode and reduce the resolution to the default system installed.

Outcome

As you can see, unambiguously answer the question why the computer monitor screen goes out during operation, quite difficult. The reasons for this may be a car and a small trolley, to find true for a regular user who does not have the appropriate knowledge, the task is often difficult to be difficult. Check the settings of the system, contacts and load on the components - this is probably for everyone to do with the diagnosis and repair of equipment, then it is better to trust the specialists from the service center.

Question: The monitor goes out (all similar topics read)

Good afternoon, dear members of the forum. I hope for you t. The situation is amazing. As in many similar topics I read on the forum, my monitor goes out. It goes out with a periodicity for a few minutes, goes out for a second - two and light up again, while the device is turned off. At the moment I reinstalled Windows three times, three different official images. The systemist was carried to the diagnosis - all the rules, the test himself than only can be. Reinstalled about 20 versions of the video card drivers, which is interesting with some blinking more frequent, every minute, with some almost stable every 10-15 minutes. I disconnected the monitor, I connected Full HD TV and I work 3 days on TV - no glitches, beautiful tests. The monitor is defective tell me. And I said so. 3 days ago I took it to the service center. Today I came SMS "Defects not detected" is how? What is it at all?

I want to emphasize. The video card is new, she is 3 months old on warranty as a power supply. In this configuration, this computer worked stable 3 months. What could be?

System.
Phenom II X4 965 Black 3400
ASUS M4A88T-M
RAM 14 GB.
Gamemax 650 W block
ASUS GTX 680 4 GB
Windows 7 x64.
Monitor Samsung BX2240.

Answer: I guess I was tired of this topic. In general, I decided to change the monitor, you only need to finish the project. But still you want to figure it out. New facts appeared in the case. I changed the connection from the DVI 1 slot in the DVI slot 2. After that, the monitor for 2 days it worked normally with a small reservation, after launching Windows was blinking several times, but then it worked stable. For 3 days after launching windows, it is the Tuh, switched to sleep mode / standby mode, helped 1-2 computer reboots. In addition, it turned out that in safe mode it works without problems. And also appeared an interesting fact. I work 3D by the artist and constantly working with different applications, so in all 3 dimensional applications, it behaves fine, and when I open the photoshop, the frequent sound of shutdown / connection begins and goes out / lights up often. I tried to connect to a laptop, but with a laptop it does not want to work (the telik from the laptop works)

Question: Periodically goes out the monitor in games

The problem began yesterday with the fact that a strong horizontal ripple appeared in the games, he sinned on, perhaps who came into disadvantage, DVI cable, it was at night /, postponed today. Today, reading the forum, I decided that these drivers either the system (Windows 7), highlighted and reinstalled the drivers on the video card (Radeon 5770), did not help, then reinstalled Windows, also did not help. He began to mess with the cable (stupid, but changing the plugs in places, ripples a little less). He began to suffer from setting up as a result of the configuration of the video card and the monitor, made the default and in games, on minimal and + by default. But now began to go over the monitor, directly in games, and further avalanche, and when you will install or go out On the desktop, everything becomes normal. The video card is not heated as well as the processor and everything else. My assumptions either a video card or a power supply (in which he doubtively doubt). I ask for the help of local experts.

Answer: Put another video card or check the monitor on another PC.

Q: Gas the monitor

Good day! When loading and operation, the Samsung Sync Master 710 monitor goes out. In the state, the green light is constantly lit, it turns on after pressing (off and on) the power button. Sometimes it turns on after the movement of the mouse. Tell me what could be the reason?

Answer: Perhaps, because the monitor is already not new ... Thank you.

Question: The monitor goes out and the computer hangs

Suddenly began to go out the monitor and reboot the computer. The computer is used mainly for the work of the accountant and surfing the Internet. The computer is not mine but parents.
I thought that the problem in the power supply was thought, took a worker-working BP for the weekend from work, the problem did not disappear. He began to sin on electricity bought UPS, set, did not help.
Comrade asked to update the computer, bought everything, connected, set up. To check it installed it from the parents works without problems does not reboot.
Then he changed the motherboard in the parent of the parents, the computer began to issue problems with the disk, i.e. Bads and all that took another disc, did not help, the computer stopped rebooted, but a new problem appeared goes out the monitor and hangs tightly. You can restart only power or with a long press button on / off. Those. Also in nutrition
I thought about the problems with the RAM, I put the company from me collected for a friend, the same thing.
The computer can work for half an hour, can work for half a day. The problem is not in the OS, as it hangs in the same way when working with the acronis (I thought to make a disk image and reinstall the system), the image decided to do because a lot of accounting programs, and if the reinstallation did not help, I wanted to roll back to not put all this Software (client-banks, different programs with cryptographs).
At temperature, everything is fine, I checked immediately after hanging, all the boards in the system, the temperature is not high for hand, the sensors show the temperature of the processor 23-25 \u200b\u200bdegrees, i.e. Generally low ...
People help, already broke the whole brain ... Which way to dig at least.

Answer: Ok, thank you, I will try how I will do anything ...

Question: Gasnet's monitor for 1-2 seconds

Hello
The monitor goes out for 1-2 seconds. Gasnet everywhere: in games, browser, desktop. It happens absolutely by chance, it can go out once every 2 hours, and maybe not to go out a week. When goes out, the actions on the computer do not hang and continue. Now I use the DVI cable, but on HDMI the same problem. I checked the monitor on a laptop, it doesn't go out there, but I checked just a week, it may be lucky. Maybe someone knows something and tell something?

Question: NOTE Monitor (No Signal)

During the games, or simply during web surfing (much less frequently) the monitor goes out (on the screen inscription: "No Signal", the light bulb flashes, like when the PC is turned off), only the reboot helps. All coolers are spinning, diodes of food on the VGA are burning, the mouse with the keyboard also remain under nutrition. Sometimes it happens that the NVIDIA driver is simply dropped (the video driver stopped responding and was restored).
The sound works, I can communicate freely in Skype, TC ...
PC collected 2 years ago (all new, except for BP), worked for a whole year without interference, then a given problem appeared, or from Win10, or from BP, whether from the HDD, or from what.
Replaced HDD, the problem remained, before replacing the BP, in addition to the drop in the monitor, the sound also hung and sometimes the computer did not respond to the reset and launch buttons.

Accelerated the CPU and the RAM, at the tempo. There was no effect on the CPU of 56 degrees, there was no influence on the problem, in Furmark, the VGA chased, in stress 64 degrees dough at low (15-20) FPS, with MSAAX16 81-82 degrees stably on 35-38 FPS, without artifacts and monitor drops. I haven't been driving with merteste, and it is generally weakly believes that everything worked stably and then suddenly failed, without any overheating and physical. influences.
Games recording increases the chance of the monitor drop. The driver from the NVIDIA site is more likely to cut the monitor than recommended for the card from the ASUS website, but the driver from the NVIDIA site does not cause an error "the video driver stopped responding and was restored."
Before replacing the BP, the voltage at the CPU was sometimes falling, as was warned by the Material Software.
Can an unstable network (weak voltage jumps) in the house for it? (Such as BP is protected from this)

Answer: The problem appeared on the other video card, then is it mother? Disted input devices during the first reboot.

Question: FPS sharply falls in games and goes out the monitor

Good day / evening / night. I am completely desperate, I'm already tormented by the 3dd day, I ask for help, suddenly someone has been in such a situation.

Problem description: When you start the game (it doesn't matter, it happens randomly, but with demanding games faster) a minute later (on the example of the game Dirty Bomb) FPS begins to sharply fall and goes out the monitor with the characteristic sound of the notification. The monitor is precisely goes out, as if the video card or motherboard loses each other, I suspect that the Windows subsequently turns off, but not sure. It happened otherwise, yesterday the game was launched by 6 hours to a row, and nothing was extinguished, but everything was repeated in the morning immediately after the PC is turned on.

I have been tormented by the 3rd day, during which time I managed to: put the drivers of different versions, completely delete the drivers and put on clean, twice reinstall Windows, update the BIOS, play a bunch of forums with monotonous answers that did not help (he created the topic for the first time).

At first I thought overheating, but why then the monitor goes away immediately after turning on the game in the morning, after the night parking lot, the computer would simply be boosted (I can definitely be mistaken). I thought the driver, but I rearranged Windows twice, and put the firewood of different versions, the effect is the same. Thought the video card, the width of Vidyuha is the same 1 in 1, put it vidyuhu, the same black screen.

Friends put forward the power supply version. But then it is not rapidly why he allowed to work for several hours, then Gas immediately after turning on the morning.

Question: When calling the mobile computer goes back

Here is such a chaos! For the first time I see such miracles))
The order is such - mobile lies in 20 cm (maximum) from the monitor. The call is received on the mobile - the monitor on the computer is turned off by 3-5 seconds, then turns on, following the rules.
The farther the phone from the monitor, the less likely to disconnect the monitor.
Win7 Prof x64.
HP COMPAQ LA2306X Monitor
A small feature - the monitor is connected via KVM Gefen.
Help the tips, please! Where to dig, at least.

Answer: Cable which monique is connected. Try to change.

Added after 7 minutes
I confirm that before getting an SMS or a call to the phone (usually lies next to the laptop) and the sound is turned on - I notice some "Tick-Tick-Peak-Peak" roughly speaking "second to"
If it lies on charging - this is a meter of one and a half from the laptop - then this is not noticed. Here is such a leap.

If the monitor is turned off during the game, but the PC itself works, not always the essence of the problem lies in the monitor.

The problem may be in an error of connecting, faults of the video card, or other components, as well as for other reasons. Below we consider the reasons why such a popular trouble may occur.

Since the monitor display goes out during the game, however, the computer works, it is necessary to start checking the most obvious cause of the problem.

Initially, you should turn off the PC, and then turn it on, watch the monitor.

When a computer is turned on, the monitor cleared and darkened immediately? Perhaps here is the case in lighting lamps that are installed in LCD monitors. They could completely blown.
The display of the monitor is dark, but when the backlight is evolving under the lamp, is it very flexible? Surely, the point here is in voltage inverter faults.

To understand what cause is a malfunction, disconnect the monitor from the system unit. In the event that the inscription "No signal" or something similar to the display does not appear, then you can not do on your own forces.

Repair can solve the problem. In the worst case, you will have to purchase a new monitor.

Disconnect display

Your monitor turns on, works perfectly, but after 15 or 30 minutes it will immediately go. What is the problem?

By default, a special "Disconnect the screen after a certain amount of time" is installed in Windows. It's all about it. "It just can not be!" - Many will say. Maybe. But it should be checked.

It will be stupid if, because of the like trifle you will spend a bunch of nerves and time, trying to find out why the monitor goes out during the game. In addition, the check itself will take no more than 2 minutes.

Instructions for Windows 7

Select the following item: Start - Control Panel - Power Supply.
Select the Power Plan Setup tab.
In the "Disconnect" tab, select the "Never" field.

On Windows 8 and 10, the procedure is almost the same.

Instructions for users of Windows XP

Right-click on the desktop, select the item "Properties".
Go to the "Screensaver" point.
Press the "Power" button (right below).
You see the "Disconnect" field, select "Never".

Humidity

Another very popular reason why the monitor turns off during the game - humidity. You can not believe, but if the laptop or PC stands for a long time in a room with wet air, it causes certain failures in its work.

As a result, the monitor turns on and turns off quickly. All because condensate accumulates in it, which, of course, will not give anything well.

What to do in such a situation? Do not turn on the computer for a while, give water to evaporate. Thus, you solve the problem (if, of course, it is in it).

Have you been cleaning a laptop or system called for a long time?

The problem is old as the world, but nevertheless. How long have you been cleaned with your own personal computer? If a long time, then the problem can be just in it. And now you are trying to understand why the monitor goes like immediately after downloading the game.

Dust can interfere with the operation of RAM or video card, so it is desirable to quickly clean the systemism. Either to attribute it to the nearest service center - let it be cleaned there. Freds do not start the computer to such a state.

Bad connected wires

Another reason why the PC monitor is turned off during the game - it is badly connected wires. The speech here is about cord from your monitor to the system unit (if more precisely - to the video card).

Perhaps you accidentally hooked it, twitched.
Maybe it did any of the members of your family, and maybe a favorite dog or a cat.

In any case, it must be checked first. For this:

Disconnect the wire on both sides.
Purge and wipe.
Then plunge it again.

It can help. Initially, it is advisable to turn off the cord only by the monitor. In case, "no signal" appears on it, then there are two news for you. Good - everything is fine with him, he did not break, bad - it is still unknown, why the monitor turns off during the game.

Another popular problem is damage to the cable. In order to test it, you need to find the same cord, connect it.

Problem in RAM

A rather rare situation, but it happens. If the monitor is cut down at the moment of the game, it is possible that your RAM simply failed, or you installed a new RAM, which is not compatible with your processor or motherboard.

In the first case, it is advisable to perform the diagnostics of RAM through a special program called Memtest. With no compatibility, only a complete replacement will help you.

Video card

Often the monitor goes out because of the broken video card. After all, just this element is responsible for displaying the image on the display. And the cord from the monitor is connected to it.

The most reliable method is to make sure that the monitor sweeps down due to the video card - connect another, try to turn on the PC. You can take it from acquaintances or friends.
As another option, you can connect someone else's monitor (again - it must be borrowed from friends). In case this possibility is not, then simply skip this step and go to the next one.

It is possible that the monitor or display on the laptop is turned off due to strong overheating of the video card. A cooler broke (a special fan), does not cope with its task cooling system.

In order to make sure that you turn off the personal computer and wait half an hour or more. If the problem was in overheating, it should be engaged in standard mode. In this case, it will be necessary to resolve the issue with the cooling of the video card, or its replacement.

Conflict Drivers Video Cards

Another frequent reason, due to which the monitor is turned off during a favorite game - this is a conflict of video card drivers. In order to check this, you must perform the following steps:

Start - Control Panel - Device Manager (For more convenience, you can select the viewing mode in the upper right corner called "Large Icons").
In a new window, click on the "video adapter", after that the name of your video card will appear.
Click on it with the right mouse button, select "Properties" and see the condition. If the video card works normally, in the new window it will be written.
Select Resources and read whether there are no conflicting devices.
If everything is fine, close all windows. Click on the desktop right click, select "Display Resolution" and select Minimum - For example, 800x600 pixels. Click "Apply" and restart the personal computer. If he turned on - the problem is completely eliminated.

Driver video cards incorrectly works

If the device is not working normally, conflicts were found, or the previous method did not help you - then we will act more aggressively:

Again, download the computer in secure mode and go to the Device Manager.
Open the "Video adapter" tab and find your video card.
Click on the right mouse button and select "Delete" (this is the standard procedure for deleting the selected driver).
Confirm deletion and restart the computer. It should start in normal mode.
Install the driver on the video card from the disk that comes in the kit, or download it from the official website.
Once again, restart the PC in order to make sure your monitor no longer goes out.

It is desirable to install the drivers exclusively from the disk.

Processor or motherboard malfunction

Probably, this is the worst possible options. It was the processor breakdown that, or a short circuit in the motherboard often lead to the fact that the screen quickly swears, and the computer continues to function.

Systemist may still work. In particular, the coolers will be used to get used, creating the illusion that everything is fine. But in such situations it may be necessary to replace the motherboard or processor, and it will already have to fork.

Nevertheless, problems with the monitor could begin for other reasons, but in this particular case it is desirable to entrust the diagnosis of the computer to experienced specialists.

Monitor resolution

In 90% of cases, such a problem begins to disturb users due to the fact that they have established very high settings for their monitor.

Each separate model supports only a specific resolution, as well as the update frequency. If you select the parameters that exceed its capabilities, then during starting the game the screen goes out.

There is a special inscription "Outside range".
The display becomes just black.

For owners of old monitors

However, there is another important point. And it arises, as a rule, owners of older monitors with a resolution of 1024x768, or 1280x1024 pixels.

The thing is that the default developers are prescribed a specific resolution in their creations. It is usually much higher than 1280x1024 pixels. That is why the monitor is turned off in the game. It simply does not support too high resolution (or update frequency).

This problem was observed in S.T.A.L.K.E.R, Far Cry 3, and other games. Then many gamers complained that the screen goes out at the time of the game.

Solve this problem is simple enough:

It is necessary to find the configuration file. It can have a different name, but always has format.ini. He is in the game folder or in "My Documents". More precisely, you can learn in Google by the name of the game.
In the configuration file, you should find a string in which the resolution is indicated, and then change it to your, save.
Everything can be played.

Thus, the problem when the computer does not bother you in the games in the games.

Conclusion

We really hope that one of the above methods helped to solve the problem. If the monitor display still goes out - then maybe the reason for faulty equipment. In this case, it is better to look for other solutions to the problem, or immediately go to the service center.

If there is a periodic shutdown of the screen when operating the computer, then the reason for this problem does not always lie on the display itself. It can be related to the video card, the connection cable, the operation of RAM, etc. The causes are many, and this article is dedicated to the consideration of the main of them.

Problems with a constantly disconnected display refer to the most difficult. To diagnose and identify the reason at home the usual user is very problematic. Such violations are related or with hardware, or with software malfunctions. The first, as a rule, require access to the service center, and the second can be learned to identify, having studied this article.

Cause 1: Monitor Malfunction

If the monitor turns off when the system unit is running, then it is not possible to exclude problems with the main output device. Most monitors have protection, triggered automatically when overheating occurs. But with standard means to check the temperature of the device will not be possible. Therefore, here you can advise only to check it on the touch. If the display housing is too hot, it should be put away from the wall or another place with the best air exchange.

Increased humidity level is one of the reasons for the periodic displays. Transfer the monitor to the room where there is no high humidity and let it stand for time. The monitor should not be connected to the network. And if corrosion still did not have time to form, then after evaporation of all moisture, the device should return to normal operation.

Disconnect the output device from the system unit. On the screen you should see the inscription like "no signal" or "missing connection". If there is no such message, it means that you need to contact the service center.

To remove the monitor from the circle of potential causes of the problem, you just need to connect another output device to a stationary PC or laptop. If the image is still missing, it means that the wine lies on the video card or cable.

Cause 2: Cable Defect

To the most common reason for the periodic shutdown of the output device refers to the cable damage. Most often, for output, DVI, HDMI connectors are used. But still meets the VGA format. You must make sure that the inserted cable holds securely and twisted on both sides (DVI).

First you need to try to connect the display to another computer using the existing cable. If there are no changes, just replace the cable.
If the cable change does not solve the problem, therefore, a malfunction in the monitor itself.
If after joining another computer, the fault disappears, then the problem has no relation to the display or the cable. In this case, seek the reason implies in the depths of the system unit.

Cause 3: Video Card Malfunction

Another logical reason for constant shutdown screen of the monitor can be a hardware faction of a graphics adapter. For such cases, the following is characteristic:

About what should be done in such cases, read below:

Cause 4: Overheating Video Card

In all modern PCs (including laptops) on motherboards are located at once two graphics adapters: internal and external. In the default BIOS settings, preference is given to that video card, which is considered to be more productive (usually discrete). Therefore, it is necessary to monitor the temperature of the external graphic module.

In most cases, the normal operating temperature of the graphics adapter is the one that does not exceed 60 degrees Celsius. But on powerful video cards to achieve this almost unreal. The maximum peak (load 100%) is usually determined at the level of 85 degrees. For individual GPU, the peak maximum reaches 95 degrees.

Almost for all existing GPUs the maximum allowable top limit is 105 degrees. After that, the graphical module of the board for cooling reducing the frequency. But such a measure may not give the result and then the PC is rebooting.

First of all, you should make sure that the video card is not cooled properly. For this, there are, for example, temperature monitoring software. Consider two of them.

Method 1: GPU-Z

Method 2: Speccy

Consider the main reasons leading to insufficient cooling of the graphics adapter.

Dust

If the PC has not been cleaned from dust for a long time, then it's time to proceed to this. There is a chance that dust inside the system unit or on the cooler of the video card does not allow the latter normally cooling. Dirt and dust on the cooler of the map in particularly severe cases can lead to its stop. Cleaning from dust does not require special skills: you need to disassemble the system unit or open the laptop housing, then use the vacuum cleaner or a soft brush. It is recommended to carry out this cleaning at least 2 times a year.

Design features of a laptop

Some laptop manufacturers already at the design stage of a certain model do not form a reliable heat sink system. In such cases, portable computers are, for example, very small grilles on the housing, which logically leads to the constant overheating of the entire device. Here you should take care of putting a back (or in front) under a laptop any stand, lifting it.

Alternatively, you can use special cooling support for portable PCs. They allow you to more intensively drive the air through the computer. There are models running from USB, as well as having their own battery.

The heat transfer between the GPU and the cooler is carried out by means of a special intermediary - thermal paste (or thermal interface). Over time, the substance loses its properties, which leads to insufficient cooling of the graphics adapter. In this case, the thermalcolus must be replaced urgently.

Note: An analysis of the video adapter will lead to a loss of the warranty if it has not passed. Therefore, contact the official service center. If the warranty period is already behind, read by reference below the thermal interface replacement guide for the graphics card.

Reason 5: Energy Saving Mode

In the Windows operating system of all versions, there is a special service that turns off the unused device currently. The purpose of such a function is to save energy. By default, the downtime is never below 5 minutes, if it is a stationary computer or laptop. But various erroneous manipulations of the user or third-party programs can change this time to the smaller.

Window 8-10.

Windows 7

Winds XP.

Cause 6: Video Card Driver

Incorrect operation of the graphics adapter drivers does not often lead to the problems under consideration. But it is not worth completely eliminating the influence of the conflict of drivers (or their absence) on unstable displays.

We load the computer B. "Safe mode".

Press "Win" + "R".
Next enter "Devmgmt.msc".

Find a discrete map (if any) in the section "Video adapters". No yellow icons with an exclamation mark next to the device name should not be.

Using the PCM by clicking on the name of the adapter, then choose "Properties".

In field "Device Status" Normal work must be specified.

Next, go to the tab "Resources" And make sure that there are no conflicts.

If the device is displayed with problems (availability of additional icons, resource conflicts, etc.), then the adapter driver should be deleted. To do this, carry out the following:

This method is effective when problems with video adapter drivers. But unfortunately, it does not always bring results. In challenging cases, the user will need to search and install the driver manually. About how to do this, read the links below.

Tip: First of all, you should find and install drivers for the motherboard (if they are not installed), then - all others. This is especially true for laptop owners.

Cause 7: RAM

One of the most common causes causing the monitor self-off is the operational memory failure. To detect such problems there are special RAM checks on errors. Even when the malfunction occurs in a single module, it is enough to periodically disconnect the monitor during PC operation.

RAM modules are unsuitable for repair, therefore, when problems are found in their work, new ones should be purchased.

Method 2: System Remedy for RAM

Another way to verify RAM does not require additional software. In the OS itself there is a special tool.

To launch the diagnostics of RAM tools for the Windows operating system itself, it is necessary:

Thus, to determine the reason for the inoperability of the monitor, the user will need to perform a number of steps. Some of these activities relates to a simple and effective diagnosis of exception. For example, hardware problems associated with the display and cable are so easily identified. Program methods require sufficiently long time, but without them can not do to eliminate the malfunction of RAM.
