I took it down for some work one day, and just happened to take the heat sync off... This machine has a celeron CPU in it(2 in fact) well you know how you can see the tops of the PINs in the packaging material. turns out that my cooler was working too well, and I had been getting condensation on the underside of the heatsync. well that caused many pins to become cross connected, due to the oxidation of the metal. Your issue might be similar.
