agrred. Try downclocking the machine, running memtest86 and then switching cpu/memory chips/motherboard/power supply/fans/cooling in roughly that order (based on what you have available). This looks very likely to be hardware related (unless you have a very unusual set of poorly supported hardware, but that seems very unlikely). Cheers, MaZe.
