Step 5: Overheated Components

You probably heard the ventilation word a thousand times in your life, especially, when you watched the PC building videos. If your computer’s ventilation system is not so good, there is a high chance your PC will perform poorly or even crash itself after a certain period.

Why?

Without having proper ventilation on the components inside triggers a RAM or graphics card, or both to be overheated. It then pushes the other parts on the computer to be heated. Sometimes it can make the monitor overheated, and that causes the monitor to go black for a moment.

So, you need to clean the monitor and the components inside a computer and give your machine a proper rest. Besides, check the fan is working fine inside the laptop or CPU of a desktop.

Click on the Display adaptors and press the right arrow to open the graphics drivers.
Double-click the graphics card and move to the Driver

Configuring with original boots is a know solution process in this case. Try the following methods to clean boot Windows 10:

Tap on the Disable all option and select OK.

Note: It will deselect the checkboxes for all the third-party services.

Restart your PC and have a look if the problem is gone.

Step 8: Disable some clashing apps

Sometimes a third-party app can cause unimaginable damage you can bear. So, stop some third-party apps and check if the problem remains. If it does, then you’ll know those were not the problematic ones. So, here’s how you can uninstall apps or features:

Press the Windows key and select Settings.
Enter Apps > Apps and Features.
Right-click on the app you want no more and select uninstall.

Thus, uninstall one app at a time and check when the problem vanishes.

Step 9: Stop Overclocking

Overclocking allows your device to perform tasks like rendering a video or architectural structure faster than the usual time. As it is a blessing most of the time, it can also cause some adverse effects on your machine.

So, stop overclocking as it gives excessive pressure on GPU that can cause your screen to turn black for a while.

Step 10: Attempt with the Wake-up Key

Up to this point, if none of the steps helped you, I suggest you apply the wake-up shortcut. Press Windows key+Shift+Ctrl+B altogether, and then you must hear the beep from the speaker if it works fine, I mean. Have a look at your computer and look if the problem is gone.

Step 11: Install the Latest Windows

Last night, my roommate couldn’t analyze his thesis for this pathetic black screen problem. He asked me to solve his problem within 15 mins.

I ran all the procedures perfectly, one after another, but it all went in vain. So, finally, I installed the latest update patch of Windows on his PC and thus solved his problem.

In any system, there can be hidden or newcomer bugs and errors. So try installing the latest Windows update patch to solve the bugs and errors in the system.

Here are the steps to install latest windows:

Press the Windows key and go to Settings.
Click Update & Security and then choose Windows Update.
Press the Check for updates option and confirm any command prompt appears.

Give it some time, and your PC will update itself automatically.
