It does sound like a hardware problem of some sort.  You should
install the memtest86+ package, reboot and then run memtest from the
boot menu.

If it can run memtest for a few hours without any errors at all, then
it's (probably) not hardware and you can start to look for BIOS
upgrades, microcode updates and the like.  FWIW the last time I had to
upgrade the BIOS on a machine, I had to download a CD image (ISO) from
the manufacturer's website, burn it and then boot off that CD.  No
specific operating system was required (it looked like the CD had
FreeDOS on it).
