Hi there, about 6 months ago my Pc started to randomly restart/ freeze. Sometimes 2 or 3 times a day or sometimes not at all for a couple of days. have tested the cpu, graphics card and ram with no issues. All my drivers are updated along with my bios. Also tried starting afresh with a wiped ssd but still occurs. Can happen at desktop while not doing anything or when gaming.

That PSU doesn't have the best reputation, so bet is that the solution is to replace the PSU.

Replaced PSU but the issue still occurs. Something I forgot to mention is that sometimes when it restarts the display resolution becomes extremely pixelated. Cant revert it wihout restarting manually.
