Ages back, I had an Intel Celeron (Sct 478 ) 1.7ghz, it suffered a few years of me overclocking it and ultimately , I sold it to my sister as a complete PC.
a good 2 years later, she calls me out of the blue to say the pc's dead.
I went round to have a look.
I powered up the pc, hitting "del" to get into setup on the bios, and went downstairs to make a Brew!
