Restarting problem with my Omen 30L

[TopKek1586]

So a couple of days ago my PC started to randomly restart, meaning my display cuts to a blackscreen, then my keyboard turns off and then I see the reboot splashscreen.
Ive been trying to solve my issue the past days but to no avail, I tried downloading diffrent drivers, reinstalling windows, checkdisk and sfc/scannow, uninstalling my 3080 and installing older drivers, cleaning my pc and much more but nothing helped.
I also checked CPUZ and other software but all the numbers seem to align with what they should look like so no abnormalities there.
Ive also noticed that it only really happens on higher loads as when I play something like Left 4 Dead I played up to 4 hours without a restart but when I started blender my PC crashed after around 10 minutes.
Which brings me to the conclusion that my PSU or GPU might be broken or faulty.
I need my PC to work as I need it desperately for my work and I hope I can resolve this within the next week.
Thanks for all replies.
