I know that a spontaneous reboot is one of the symptoms of an unstable overclock. You haven't said you overclocked your machine - if you have drop it back a couple of MHz external frequency or drop the CPU multiplier by 0.5 or so.

If you haven't overclocked your machine, check your BIOS settings incase you've accidentally set your CPU up wrong. THIS is the link to a .PDF of all Athlon CPUs. Check it's all good.

Failing this, maybe your memory is bad. I don't know if that could be the cause of your troubles, but trying it with another stick will at least eliminate the possibility.

Apart from checking your CPU setup in BIOS, I don't know what's up with your machine. Sorry.
