Windows 10: What else could cause displays to randomly go black for a moment and occasionally freeze up...

There is one desk in our office in particular that has an ongoing issue with monitors briefly going black at random intervals. We haven't been able to find a solution for almost 2 years now.

It happens on the same display the majority of the time, but occasionally will happen on each of the other two displays as well.

PC Freezing Up Occasionally

Hi！



Welcome to Microsoft Community and thank you for sharing your concern with us today.

Your problem is PC Freezing Up Occasionally. It may be that your computer is a bit old and is not compatible with the Windows system, so occasionally a black screen will appear.

We suggest that you try the following steps:

Workaround 1: Turn Off Link State Power Management

Virtual memory is a combination of your RAM and a portion of your hard drive. It is mainly used to extend your computer's physical memory. When your computer runs out of RAM, Windows uses virtual memory for temporary file storage. In case that it is the insufficient RAM brings Windows 10 freezes randomly issue, you can adjust the virtual memory.

Step 1. Right-click "This PC" and choose "Properties". Then select "Advanced system settings" from the left panel.





Step 2. Go to "Advanced" tab and click "Settings".



Step 3. Go to "Advanced" tab again and choose "Change…" under Virtual memory section.



Step 4. Ensure the "Automatically manage paging file size for all drives" is NOT checked. Then select the partition that has Windows installed (usually, it is C and enter an Initial size and Maximum size for your virtual memory:

• Initial size: This value varies on different computers. If you're not sure what value to use, just enter the recommended size.
  
• Maximum size: Don't set this value too high. It is recommended to enter 1.5 times the size of your physical RAM.
  

Once you've configured your virtual memory values, click "Set" and then "OK" to continue.



If PC keeps freezing, try the next solution.

Workaround 2: Turn Off Fast Startup

Step 3. Find your power plan and then click "Change plan settings".

Windows 10 freezes randomly

I had already tried turning off fast startup, to no avail.
Will look at the list you provided, thanks. Hard to do when computer freezes on the Windows loading screen though. *Biggrin

I had tried that as well... no result.

 

duel monitors display freezes randomly

Hi, I'm using a duel monitor setting. My laptop screen is the secondary display and my external monitor is the primary one.

Occasionally the entire display freezes randomly (both screens). When I plug the HDMI cable out and then back in, it usually works out but sometimes I have to repeat this process several times to make it stop freezing.

I have this problem for long time.

Also, I have gtx 1650 gpu and intel i7 9th Gen on my laptop.
