I use windows 11 x64 pro with asrock b550m pro rs mb.
Randomly my PC freeze..many time when i make a switch between a fullscreen game and windows desktop or when some apps in fullscreen like microsoft edge(i think there is a problem with some css/js or an addons). I use same apps, nothing new installed or changed. This problem is from the begging, i reinstalled windows many times, i changed cpu. I think is a problem from gpu. And often the screen glitters..
From what i saw, after every first restart after an windows cumulative update this is happening. Sometimes i got freeze just using windows media player or itunes, sometimes in microsoft edge using youtube.
I didn't installed that amd radeon adrenaline software.
