Turns off Windows 7 Monitor

When Windows starts, does your monitor go blank? Or does the laptop screen go blank? First it turns on, and after 1, 2 or 3 seconds it turns off? In this case, the computer itself (system) works, right?

There can be many reasons why the monitor turns off. And it doesn’t depend on what operating system you have: Windows XP, 7, 8 or 10. And it doesn’t even depend on what monitor you have: Samsung, LG, Asus, Acer or Philips. Everyone can have such a problem.

Since you do not know why the screen goes blank, first you need to make sure that this is not a hardware error. Below are 10 ways to solve this problem, and you can check them all one by one.

To fix the problem, you will need to turn on the computer. You can do this by downloading it in safe mode. To do this, when you turn on the screen, repeatedly press the F8 button until the menu appears (select “Safe Mode” in it). If the Windows logo appeared, then you didn’t have time. Restart your computer and try again.

Display off

Let’s start with the simplest. Your monitor turns on, works great, but after 10, 15 or 30 minutes it goes out. What is the problem?

By default, Windows has the function “turn off the display after N minutes”. It’s all about her.

“Yes, this cannot be!” You say. Maybe. But it’s worth checking out. It would be foolish if, because of such a trifle, you spend a lot of time and nerves trying to figure out why the monitor goes out. In addition, the check will take 2 minutes on the strength.

Instructions for users of Windows 7:

  1. Start. Control Panel. Power Options.
    Turns off Windows 7 Monitor
  2. Select “Configure Power Plan”.
  3. In the item “Turn off the display”, select the field “Never”.

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

Instructions for users of Windows XP:

  1. Right-click on the desktop and select “Properties”.
  2. Go to the “Screen Saver” tab and press the “Power” button (bottom right).
  3. See the familiar “Turn off display” field and select “Never” (or any other value).

Humidity is to blame

Another popular reason is humidity. You may not believe it, but if a PC or laptop stays in a room with humid air for a long time, it causes malfunctions in its work. As a result, the monitor turns on and off immediately. And all because condensate can accumulate in it, which, of course, will not work well.

Have you cleaned a system unit or laptop for a long time?

The problem is as old as the world, but still. How long have you been cleaning your computer? If a very long time, then the problem may be just that. And now you are trying to understand why the monitor lights up and goes out right after loading Windows.

Dust can interfere with the operation of the card or RAM, therefore it is recommended to clean the system unit as soon as possible. Or take it to a service center. let it be cleaned there. And henceforth do not start your computer to such a state.

Poorly connected wires

The next reason to turn off the monitor is poorly connected wires. We are talking about the cord from the monitor to the system unit (more precisely. to the card). Perhaps you accidentally hooked or pulled it. Perhaps one of your family members did this, or maybe even your favorite cat or dog.

In any case, this must be checked first. To do this, simply disconnect the wire from both sides, wipe (blow), and then plug it back in. May I help.

Another common problem is cable damage. To check this, you need to find a similar cord and connect it.

RAM malfunction (RAM)

For this reason, the monitor goes out quite rarely, but sometimes it happens. You may have recently bought a new RAM. Or she just got a deadline.

If you have several RAM slots, you can disable one. Or swap them. You can also check your RAM from a friend, or take his RAM and connect it to you. If the problem is in it, you will immediately understand it.

Graphics Card Failure

Most often, the monitor turns on for 2 seconds and goes out due to a malfunction of the card. After all, it is she who is responsible for displaying the image on the screen. And the cord from the monitor is connected just to her.

The most reliable way to make sure that the monitor goes out precisely because of the card is to connect another one and try to turn on the computer. You can take it from your friends or acquaintances (if any).

Perhaps the problem is due to overheating of the card. The cooler (fan) has broken, the cooling system is not coping with its task, etc. To verify this, turn off the computer and wait 20-30 minutes (more can be). If the problem was overheating, then it should turn on in normal mode. In this case, it will be necessary to solve the problem of cooling the card or replacing it.

Graphics Card Driver Conflict

Another reason is the conflict of card drivers. To verify this, do the following:

    Start. Control Panel. Device Manager (for convenience, you can select the “Large Icons” view mode in the upper right corner).

How to open the “Device Manager”

  • In the new window, click on the item “Adapters”, after which the name of your card will be displayed.
  • We click on it with RMB, select the “Properties” item and look at the status. If the card is functioning normally, then it will be written in a new window.
  • Next, select the “Resources” tab and read if there are any conflicting devices.
  • If everything is in order, then hide all the windows. Next, click RMB on the desktop, select “Screen Resolution” and select the minimum. for example, 800×600 pixels. Click “Apply” and restart the PC. If he turned on. congratulations, the problem is fixed.
  • The driver does not work correctly

    If the device does NOT function normally, some conflicts were detected or the previous method did not help you, then we will act more aggressively:

    1. Boot the PC again in safe mode and go to the “Device Manager”.
    2. Open the “Adapters” item and find your card.
    3. Click RMB on it and select the “Delete” item (do not worry, this is the usual procedure for uninstalling a driver).
    4. Confirm the removal and restart the PC. it should start in normal mode.
    5. Install the driver on the card from the disk that comes with the kit, or download from the official site.
    6. Restart the computer again to make sure that the monitor no longer goes out.

    Perhaps this will be useful to you:

    Motherboard or processor malfunction

    This is probably the worst of all options. It is a processor failure or a short circuit in the motherboard that causes the screen to go dead a second after turning on, and the computer continues to work.

    However, problems with the monitor could occur for other reasons, but in this particular case, it is best to entrust computer diagnostics to specialists.

    Why does the monitor turn off during the game?

    And finally, another problem that every gamer must have encountered during the game. over, such a malfunction can occur only when starting some toys. Pretty unpleasant situation, right?

    In 90% of cases, this is due to the fact that you have set the monitor settings too high. The fact is that each model supports only a certain resolution and refresh rate. And if you select parameters that exceed its capabilities, then when the game starts, the monitor goes blank (the message “Out of range” appears or the screen just turns black).

    But there is one more nuance. And most often it occurs among owners of old monitors. for example, square (with a resolution of 1024 × 768 or 1280 × 1024 pixels).

    The fact is that developers by default prescribe a certain resolution in games. And usually it is much higher than 1280×1024 pixels. After all, it does not support such a high resolution (or refresh rate). Such a problem was observed in Far Cry 3, S.T.A.L.K.E.R, etc. Then many players complained that the monitor went blank during the game.

    In that file you need to find the line where the permission is indicated, change it to your own, save it. and you can play.

    Instead of a conclusion

    Well, I hope that one of these methods has helped you solve an unpleasant problem. If the monitor screen still turns on and goes off, then perhaps the problem is with the faulty equipment. In this case, you can look for other ways to solve this problem or contact a service center right away. But it is up to you to decide.
