Looks like a memory problem.  Try getting the memtest86 package.  It is
packaged in Debian, but it's not actually a Linux app.  You copy it to a
floppy and boot with the floppy.  Memtest hammers hard on the ram for a
while, doing a series of checks designed to cause problems with the RAM
to become apparent.

I've also seen problems like this with bad motherboards.  If possible,
try swapping out different hardware components (i.e. try a different
video board, etc).

Good luck.
