In Desperate need of help
I've been using this pc for months now but recently I flashed latest because Faceit was not running and I was getting bootloop.
Since then nothing in my pc is changed apart from that but nowadays I'm getting random pc freezes, restarts driver errors and whatnot.
Also to run Faceit I enabled IOMMU
I've tried installing fresh win 11 but the issue is still persists.
I cant afford to show it to repair guy and it kind of goes against my pride as I've built it all by myself.
What could be the issue? How to troubleshoot it? Is there a way to flash older bios? Specs in the comments.
