Question Unexpected, random hard shutdowns

Hi All,

I have a Fedora 4 system consisting of:

40 gig Wester
Asus A8xxx mothernoard (single CPU)
1 gig All Components memory
Intergrated NIC and sound
ATI Rad 7000 series w/ Digital and component output video card
ZaLman 300w low noise power

The memory alway checks out good. The system heat protection is set high enough as to not fry the CPU, but shut down if it runs away. BIOS diagnostic says the CPU gets up to 120-130 degrees F., but not much higher.

I recently replaced the SCSI drive and power supply. The SCSI controller has been removed. Problem occurred with these in the system also, which I thought might have been the problem.

The system runs well until it shuts down hard. There is no assitance by the OS or myself. It is as if someone pulls the power plug out.

I have to bring it up by shuttting off the power supply main switch, then switching it back on from the main switch (and/or the front panel switch). It begins to come back up, shuts down for 1 second then continues to POST.

Could it be that I am using a SMP CPU with a single CPU board?

Thanks for any advice!

No, it's connected and running. I'm looking at the CPU fan right now.

Correction: it is an A7xxx ASUS motherboard.
