The usual culprits are:
- Bad power coming into the computer. i.e. brown-out situations or
incorrect voltages coming in from outside (I've seen 130VAC on what is
supposed to be a 120VAC outlet). The solution for this is typically a
power-conditioning UPS that will adjust the voltage to compensate for
over/under voltage conditions.
Note: Poor power quality from the power company can cause marginal PSUs
to fail where they would work fine in a cleaner power environment.
- Overworked power-supply. Typically only happens if you add additional
equipment to an existing case. But could also happen if the
power-supply was marginal to begin with (barely able to power the
original equipment) and has now begun to fade. A larger and/or better
quality PSU will help with this. You can attempt to troubleshoot by
diconnecting non-essential equipment (CD/DVD, floppy, secondary hard
drives, tape drives) and seeing if the PC is stable. If it's stable
with less of a load, then you probably want a new PSU.
- CMOS/BIOS battery is dying can cause odd issues sometimes. This
doesn't sound like one of those.
- Heat. Is your CPU overheating and the thermal protection circuit is
shutting the system down to save the CPU from damage? Grab a copy of
SpeedFan 4.28 from http://www.almico.com/speedfan.php and look at your
CPU temperature. Or some BIOS's have a screen where you can view the PC
Health including CPU temperature.
