Could anybody help me with this current situation i'm totally out of ideas.

I built a friend of mine this PC and it shuts down randomly but the fans keep spinning.

I tried CPU stress test and it never goes past 55c. Iv tried GPU stress test and that goes to 75c.

I used his PC at mine for 5 hours yesterday and didn't have 1 problem with it. But he says it keeps happening.

The system is as follows.
CPU - I5-3470
GPU - Gigabyte GTX 770
PSU - Corsair 650W Semi Modular Bronze
Motherboard - ASrock Z75 Pro3
RAM - 8GB Corsair 1600 Mhz.

Any help is greatly appreciated :)
