Virus attack or a Hardware malfunction?

It was the deadline for a paper and Fischer was typing away furiously on his old AMD Athlon, ASUS motherboard system. Then all of a sudden pftt!!! the computer switched itself off without a warning. Not a reboot, not a shutdown but a switch off! It was futile to attempt to switch it on immediately. Only after 25 seconds would the system reboot.

Fischer pondered on whether this was due to a problem with the system hardware or if it was a virus attack?

Upon reboot Fischer ran the program SpyBot - everytime the program completed 70% of the checks the above phenomenon repeated. Frustrated Fischer resorted to checking the hardware. On opening he found a thick layer of dust on the CPU Heat sink. Could this be the reason?

As it turns out ... it was! Dust on the heat sink caused the CPU over heating resulting in no-warning system switch off. The dust was off and Fischer's PC was back in action. Check here
