PC restarts under heavy load

Alin_8 · Jan 9, 2018

Hy!
I have a gtx 980 ti , i5 4570 ,8 gb ram. My pc restarts under heavy load , after that the screen turns black ( no signal from gpu) and I have to unplug the power . Cpu / gpu temps are good . Even after I replaced the PSU with Seasonic s12II 620w problem still occurs.

As you have changed the PSU and you are sure temps are ok my guess would be a motherboard fault but the only way to test that is using another motherboard.

Could all these restarts be caused by the gpu ?
I overclocked it but no extra voltage and the oc was stable during stress .

Could be the motherboard as already said, but also the GPU. Since you overclocked the latter, try going back to factory speeds and see if that helps.

I stressed the gpu in OCCT and computer restarted , cpu test was fine .
I think the gpu is the source of all problems.

Try lowering clock speeds. If that doesn't help, the GPU is probably defective.

I tried to lower clock speeds and it didn't worked , I can only run games like World of Tanks and Team Fortress 2.
