Well today im working away on my PC that has two screens...up until i hear a wrrrrhhh comming from the "brains" of the operation and then one of the monitors goes blank....arg!!To cut a long story short i pulled out the one of the cards in the PC to find the fan was absolutly rooted!!! Heres a pic
As you can see the fan just ripped itself to pieces and the card died mysteriously... (photo not that great sorry)
