Use memtest86. It makes a bootable CD or floppy and, once you've booted
from the CD or floppy it goes straight in to the test, thus taking
Windows out of the equation.

It's well worth a go.

Also have you had your hand on the CPU heatsink while the machine is
running to see if 49c is sensible for the actual temperature of the
chip. I just wonder if the mainboard is not seeing the true temps on the
chip?
