PC powers off

pb999 · 5 Feb 2007 at 12:38

My PC has started powering itself off all by itself.

This can happen after it has been on for an hour or five hours, it seems to be unrelated to time or temperature, which are all normal.

It has a A8N32-SLI Deluxe motherboard, with an AMD 4600+ CPU, 2gb Crucial Ram, 2 SATA hard disks, Geforce 7900GS

I have assumed that it might be a faulty PSU, but I would be interested to hear what anyone else might think before I order a new one.

Yes, it's likely to be the PSU, you don't give the brand & model?

Also it could be the RAM. Have you run memtest?

I am at work at the moment, so I cannot remeber the PSU brand, however, I can tell it that it was fairly cheap and cheerful (perhaps not so).

I hadn't thought of the memory, I will test it tonight, I had assumed that Crucial memory was beyond reproach, but maybe not...

Thanks,

Cheap and cheerfull, id say its the PSU then.

If we assume for the moment that it is the PSU, what would you recommend?

A lot of people seem to like the Corsair 520W, would that fit the bill nicely?
