Windows 10: My computer goes to a black screen and becomes unresponsive after about an hour

No matter what my computer screen goes black and becomes un-useable. I can restart it and use it again for a while but after about an hour or loonger the computer goes black screen whether I am doing something or not.

Computer Black Screen

I normally leave my computer run 24/7 but lately the computer has to be rebooted daily because it does the following:

• Becomes unresponsive with a black screen
• Network link goes down when this happens
• Computer can't be revived and simply has to be rebooted.

Event logs show NOTHING when this happens and I know the rough time when it happens because I have nagios monitoring my network including this computer and it tells me when it looses internet, etc.

I've replaced the video card with a brand new one yet this still happens. I'm thinking it has to be a bad PSU or mainboard but I'm unsure what to do to resolve it.

 

Screen goes black if the power cord is connected

Hi Tony,

As the screen goes black I suggest you to refer the Microsoft article on
Troubleshoot black screen problems and check if it helps.

http://windows.microsoft.com/en-us/windows-10/troubleshoot-black-screen-problems

I also see that you are facing issues with the keyboard this might be due to the corruption of keyboard drivers. I suggest you to run the
hardware and devices troubleshooter and check if it helps.

Follow the below steps for the same.

Windows 10 has a built-in troubleshooter to check and fix issues with hardware and devices. I would suggest you to run this troubleshooter. Refer these steps:

• Press Windows key + X, select Control panel.
• Change the view by option on the top right to Large icons.
• Click on troubleshooting and click on the view all option on the left panel.
• Run the Hardware and devices troubleshooter.
• Restart your computer and check if the issue is resolved.

Hi Kris,

It is possible that your screen goes black may be due to a critical system error which can cause the system to shut down. To isolate your issue, we'd like to gather more information:

• Have you made any recent changes prior to this issue?
• Did you get any error messages when it turns black?
• Have you tried checking if the sleep mode is turned on/off?
