Maybe the problem is bad RAM? That's all I can think of.

Subject: OT: system shuts off sporadically
> Hello everyone:
> I've been experiencing a problem with one of my PC's. Eight months ago
> I upgraded it to an Abit VIA KM400A motherboard with an AMD processor
> and new RAM. In the last couple of weeks it's started shutting itself
> off sporadically, for no apparent or consistent reason. I know it's not
> a software problem (though if anyone wonders, I've got Ubuntu on it, and
> have been quite happy with that flavor of Linux) because it has at times
> shut itself off while I'm in the BIOS setup screen. I have replaced the

> switch line. I've turned off the "halt on errors" feature.
> - In the BIOS PC health screen the CPU temperature appears to be well
> within the good range. However, I've only checked this shortly after
> power-on.
> - The motherboard is rather compact, and is mounted in a maxi-tower case
> with extra fans. I don't know for a fact if the airflow is optimal.
> - I've checked the system logs and there is absolutely no record of any
> kind of error at the time it powers itself off.
