I'm trying to put together a system for my gran from some old bits, but it's a bit unstable and turns off rather abruptly now and again. The ram and cpu I'm pretty much certain are good, so I think it's either the PSU or mobo that's the problem. The readings in bios for the voltages seem rather low:
Vcore: 1.82
3.3V: 3.28
5V: 4.86
12V: 11.67
It's a Asus one that came with the case, it's only running an socket A Athlon 1800+, 512MB ram, 1hdd and onboard everything else. Do you think the low voltages are the problem or could it be a faulty mobo?
