Instead of guessing, try memtest86 at

The easiest way to use it is download the package, copy the pre-built
binary to a floppy, and boot the node with the floppy.  It will run
until you stop it.

This should point to a memory problem if it exists.  Make sure you read
the docs, as there are some Athlon-specific comments IIRC.
