I've noticed that you have 1 GB of ram. I assume that this is 2 x 512 MB double
sided sticks running at DDR400 or more?
According to AMD documents, this configuration (4 banks of ram @ DDR400) is not
supported by your CPU (on A64s the memory comtroller is on the CPU)! I have an
Athlon64 3000+ with 1 GB of ram and I was getting strange (but not often)
crashes for more than a year.
Prime95 would get an error within 1 minute. However, Memtest86+ ran fine for hours.

Recently I replaced on of my sticks with a single sided stick (hence only 3
banks of ram) and my problems have disappeared. No more random crashes and
Prime95 can run for hours.

Try pulling out one of your ram sticks and see what happens.
I am really annoyed at AMD and the mobo manufacturers for keeping this important
limitation so quiet. My motherboard manual says nothing about this.
