Hey! I've been having trouble with my pc as of recently, and i was wondering if anyone has any fixes.

Since 2 days ago, my pc shuts itself down whenever i open larger games, no issues when i play 2d platformers but as soon as i open a game like Witcher or Marvel Rivals, my pc shuts down without any bluescreen, any alerts, just shuts down.

I've tried basically every software fix there is without any solves. i've tried Undervolting my GPU, Resetting every setting to default in BIOS, checking for corrupted files, checking temperatures, etc. About 2 months ago i had this issue and i simply moved to windows 11 from 10 and that seemed to fix it, but alas it started again

The only thing that seems to make sense is my PSU is failing, any other fixes i should try before dropping money on a new PSU? Also, any recommendations for PSU around 800-1000W ?

Hey, as the title suggests, my PC keeps shutting down for no reason, or when I launch bigger games. It started doing this only yesterday which has me very confused, I could play the Witcher 3 for hours on end and no problem, but since then my PC just shuts down whenever I launch it, no error message or anything.

Everytime I check my PC before it shuts down, the temperatures are normal. I guess it must be the power supply? But it surprises me that it became obsolete overnight. Is there any other possible fixes before I go buy a new PSU?
