If it's not the RAM, it's something else hardware related (the HDD has
been
re-imaged multiple times in its entirety and all extraneous boards and
peripherals have been disconnected).

What other hardware diagnostic stress-testing freeware can you further
recommend?

Why settle on a hardware problem without proof? In my experience a bad
driver or glitched OS is equally likely if not more so. Try booting from
a Linux CD/DVD/STICK and run it for at least a few days and see what
happens.

You can run Prime95 from Linux. That's my favorite.

Normally you'd do that to avoid corrupting the
registry on an (unstable) Windows install. You should
not run Windows or do Windowsy things, until
"proving it's a computer" first.

The Linux ones are static. Which is what you want.
Nice and portable.

Make sure your CPU cooler works first, before
running that. Or, the power will go off on overheat
(THERMTRIP).

Paul, if they are saying they're not responsible, who is? Will you
chip in if I lose the prize I should have won?

It's a contest, if you snooze, you lose.

First person to evaluate a number and determine primality
claims the prize. Someone also duplicates the effort, as it
looks really bad if a prize is claimed for no reason.

I ported a piece of code using GMP (bignum package), and
it runs at a lethargic pace. Not with the speed of the
FFT method used by the "Prime Guy". However, if you use
Prime95, then the money you get is reduced, as it's
a pool of sorts.

If I used my home grown, slow as molasses program
(does math with 40 million digit numbers), and I happen
to finish first and notice a particular number is a
Mersenne Prime, then I don't share the money with the
"Prime Guy". Maybe I get the money and you don't. However,
i can only evaluate a single number, once in a blue moon,
so I'm not much of a threat. My computer can only do around
twenty 40 million digit calculations per second.
