Hi there,

Last week I came home to find my PC off, and noticed that the clocks around the house were wrong; so it seems we'd had a power cut while I was out. Since then, I haven't been able to turn my PC on.

The PC turns on for a few seconds, the fans spin, and then reboots after a few seconds. This repeats until I unplug the power cable.

There are no beeps.

After doing a bit of reading around, I thought the PSU was the likely candidate. However, I've tested with a working PSU and have got the same result.

I've also used the jumper pins to clear the CMOS, but still the same result.

I've had a look at the motherboard and can't see any obvious bulging capacitors or damage.

Bit unsure what to try next - does anyone have any ideas?

Some digging online seems to indicate it's the motherboard, but I don't really want to shell out on a replacement if there's the possibility of it being a more simple issue.

Does anyone have anything else to try?
