BIOS Settings...

[AMDX23800+]

Today i started up the computer, it started for like 20 seconds, then turned off and restarted itself, and it had changed the overclock settings in the BIOS back to standard by itself :S
Why would it do this?

Unstable overclock, re-do the overclock but try a little lower, then start working your way up. But check your memory speed and you might need a little more volttage on the cpu.

memory speed is as standard at 1066mhz.
I have also done stress tests, seems stable! I will up the voltage slightly.
