This is not a symptom of a "fried" processor. It could be the processor shutting down due to being too hot. If your FHS pins need to be replaced you can replace them of get a new FHS with TIM.
Your FHS/processor needs to have some force and TIM for proper thermal heat transfer or the processor will get hot and (prochot) will shut it down.
thanks for the reply tmsimmon. how long does it take for a quadcore to het up to dangerous levels as my machine turns off after about a minute.
Contach Intel CUstomer Support and have them send you out a pack of push pins. ..."one of the plasic pins on the stock intel cpu cooler is damaged so doesnt fully press the cooler onto the cpu." Yes that could be your problem and have them send out some TIM too!
