Found that the issue was insufficient power supply, so upgraded to an 850W Coolermaster Real Power Pro.
But now my computer won’t shut down. :O
I’d shut it down, and 5 seconds later it wakes up again. Creepy! I checked my BIOS APM settings, XP Recovery settings, XP NIC WOL settings, updated my BIOS, but to no avail! I even unplugged everything except power and it still restarts. I unplugged my casing power switch and it still manages to stay alive. :O :O
