I'd start by running memtest86 on it.  Your oops:

isn't actually anything to do with ext3; rather, the "copy_files"
function is an internal function which copies the the list of open files
from a parent process to its child when a process forks.  Getting an
oops there is usually a sign of memory corruption, and the

errors are consistent with that.

You said you've changed the memory, but it could be many other problems
--- a CPU fault, the CPU overheating (check the fan!), cache problems, a
chipset fault --- contributing to the memory corruption even if the RAM
itself is fine; or the hardware might be perfect but the BIOS settings
wrong.  memtest86 is definitely the next diagnostic for you to try in
this case, as if that shows an error, you know it's definitely not a
kernel problem and you can start narrowing down which part of the
hardware is causing the trouble.
