Question PC crashes in games/stress tests unless pc is on power saver and has -0.100V offset.

[AridNexus]

specs:
CX750M
i5 6600k
R9 390
MSI z170a gaming pro mobo
2 sticks of 8gb ram of different company
Everything is about 5 years old

So my pc crashes whenever i play a heavyish game by shutting down with a beep sound and then rebooting. No BSOD.

At first i thought my cpu was overheating and so i bought a cpu cooler which lowered the temps from 75 to 60 while under load. But then the issue still continued on games such as hitman, deus ex, and starwars fallen order. It wont crash when playing games like csgo or valorant.

The only way i found to fix this issue is by putting my PC on power saver mode and have a -0.100V offset. But from time to time my PC still crashes. Keep in mind my PC is not overheating and crashes 2-3 minutes into any game. I tried switching out the RAMs to see if they had a problem but the issue continued. I also switched to connecting my pc psu to the wall outlet but that hasnt done anything.

At this point i suspect its an issue with either my cpu, mobo or psu. Please do help as i am very frustrated.

Remove the offset

Remove the offset

Thats the thing, the offset is what prevents my PC from crashing. Removing the offset will only make my PC crash

Sounds like a faulty PSU but should wait for other replies before you look to replace it.

Would a psu failure have my pc shutdown with a beep and reboot?

Yes. It can also randomly crash games and programs without shutting you down.
