Check your memory dude.. especially for EDO/NON-EDO combinations.. i had
the exact symptoms you're talking about with my pc about a year ago..
memory tests still came up OK, computer would crash/blue screen after a
while of using it (ie when the lower half of my memory filled).. it seemed
to me for ages that it was an overheating problem, but after swaping out
various bits of hardware, it ended up being the memory..
if all your memory chips are the same.. try swapping all of them for some
other known working ones and see how it goes..
