Question My computer crashes after using anything in full screen

[AbrahamLincon]

I bought a new computer and kept my old ssd and gpu with it but have been troubleshooting the same issue for 10 hours straight now to no avail. Whenever I open an app or game in fullscreen or borderless window my task bar freezes and nothing will work but I'll still be able to move my mouse around. I've tried basically everything from completely deleting my graphics drivers using DDU, disabling fullscreen optimizations, messing with refresh rates, scanning for corrupted files, adjusting TdrDelays and basically anything I could find that could possibly be the issue. If someone could please figure out why this is happening it would be greatly appreciated.
Trying to restart windows explorer doesn't work either

You forgot to mention the make and model of your PSU and it's age. Please mention the BIOS version for your motherboard as well.

Did you reinstall the OS after your platform migration? If not, that's the root of your troubles.

My PSU is an MSI mag A650BN and i bought it only 3 days ago. I'm not sure how to check my BIOS version. I was also never prompted to reinstall windows when I first booted and now it says windows isnt activated. is there a way to do so without having to spend 200 dollars on another windows 10 key?

if you just plugged in your old windows install SSD into your new motherboard windows will attempt to load but it will think you have two sets of hardware. One set from your old motherboard that is not responding and another set that plug and play detects and installs drivers for. normally you would want to do a clean install of windows but you might be able to go into windows control panel device manager, find the menu option to show hidden devices. Then go thru the list and delete all devices that are greyed out. then boot into bios and update the bios or make any change and change it back and save the bios config and reboot.

after you reboot go to your motherboard vendor and update drivers. be sure to update the motherboard sound driver even if you do not use it. update the cpu graphics driver also.

check the power connections from the PSU to the GPU if you have external power connection)

most people would reinstall windows rather than repair.

you might consider running cmd.exe as an admin and run
dism.exe /online /cleanup-image /restorehealth
this can be useful if your windows install has been corrupted/hacked
