Help with pc issues

[Ruprekt79]

Hi all.

My son has a pc with the following spec:-

I7 930 water cooled
Gtx 1060 gigabyte g1
8gb 1600 ddr3

Before Christmas he was running the same pc but with a hd7770 and an older psu. Before we added a new psu and his gtx 1060 everything ran fine. But since we installed his new psu and gpu he has random crashes within games as well bsod and the pc stalling on windows every now and again.

I have reinstalled windows, changed his hdd, reset bios to default, tried my gtx 970 in his pc, ran memory tests, cpu stress tests, checked temps on all components etc and the pc is still having the same issues.

My only thought now is that his new psu may either be faulty or not working properly with the demands of his pc. The psu is an Oem CiT 550w. I know this isn't the best psu.

Any help at all would be really appreciated. If anyone thinks it could be the psu I will try a new one.

Cheers.

Thanks all for feedback.

His old PSU, I don't have it anymore but I know it was a cheap 500w Antec. Reason for getting the new one was that his old PSU didn't have a 6+2 pin for his new GTX 1060.

The problem I have now is I delved into his BIOS yesterday and reset settings to fail safe defaults and since then he's getting a blue screen saying bad system config. Does anyone know what settings may have changed within his BIOS which is causing this new error on loadup? Failing that I will have to reinstall his windows again and then try my PSU in his.

Cheers again for the help. The GTX 1060 was his Xmas present so am really wanting to get this working for him as soon as I can.
