Windows 10: Computer froze, then certain colors started to look blurry after a restart.

To explain, curved edges are now pixelated, and certain colors look like they are being shown at a different resolution. I have already tried changing the resolution and changing it back. It worked, but set the monitor's refresh rate to 60hz. Changing that back to 120hz caused the issue again. It is only occurring on a 2k monitor, the 1080p secondary monitor looks fine. Changing the resolution of the main monitor down to 1920 x 1440 fixes the blurriness, but of course I don't want to be unable to use part of the screen. 2 restarts did not fix the problem. My RTX 3080 has had some issues with causing the monitors to go black for a few seconds, but I'm guessing the PC freezing had something to do with this. I am going to be replacing it with a new 3080 soon, but I don't know if that will fix this problem. I reinstalled the latest GPU update, but did not remove that update first. I will include 2 screenshots from both monitors on the same screen to show the difference. The first is with the 2k monitor at 120hz, the second image is at 60hz. Looking at that on my 1080 monitor, both look the same... so it is only present on the 2k monitor. It is the most obvious with things colored red, orange, and other similar colors. In the NVIDIA control panel, the color format seems to be set to YCbCr422 for the 2k monitor, but RGB on the 1080p one. I tried to change them both to RGB, but it was instantly reverted. The game I was playing at the time was an older game, and it definitely did not originally launch at 2k, so maybe it not closing properly caused something. I remember that used to be a problem on older versions of Windows.

Colors looking grey in Windows 10

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that the colors look grey on your computer. I would suggest you to check the color filters in Settings and see if that helps. Kindly, refer the steps mentioned below:

1. Press Windows key + U, to open
   Ease of Access Settings.
   
2. Now, select Color filters from the left pane.
   
3. Under Use color filters, toggle the switch to
   off for Turn on color filters.
   
4. Clear the check box for Allow the shortcut key to toggle filter on or off.
   

Let us know how it goes.

Computer hangs up/freezes when running certain apps

Hello

A few weeks ago my computer started completely freezing. When those freezes occur the computer is totally unresponsive and requires a reboot, however they only happen when running certain programs.

Windows Version number : 1903
When does it happen?

• Playing youtube videos (takes a few minutes to freeze on average)
• Starting certain games (freezes on startup)
• Answering discord calls

And i discover new sources all the time so i doubt this is a complete list.

What did i try so far?

• Updating the drivers (didn't try to update the BIOS yet but reset it to default)
• Sfc / chkdsk
• OCCT (both CPU and GPU test, neither overheated/froze the computer)
• memtest x86 (4 passes 6 hours, no errors)
• Swapping GPU (RX-480)

By this point i was a bit lost so i tried using windows event viewer to no avail.

As a last attempt i tried to install windows on a new harddrive but the computer froze during installation.

I'm completely lost and don't know whether my hardware is failing or if it's some kind of software issue.

 

Random restarts

when you start the computer up press F8 repeatedly until you get a list of how to start windows, choose do not automatically restart on system failure. if your getting bsod's list what your getting here so we can further help you. IF the system is not getting bsod's and still restarting as you say then i would look into getting a line conditioner for your computer as you might be having power issues.
