Have you done Memtest86 for a day or more?  (see
http://www.memtest86.com/)

What about bios upgrades?  

Different motherboard (same K7VTA3 model, just a different physical MB).

Memory interchange?

What memory did you buy:  brand name or the cheap stuff?

What is the CPU temp?  The chassis temp?

On one of my ABIT KR7A systems, I had to increase the memory voltage and
the CPU voltage to near the maximum in the bios list to get the machine
to run stably.  Dont do this if you have poor cooling.
