Hi there have a realy weird one here, I was happily playing a game on my pc when off it went no error messages nothing, I tried to turn it back on but only got a light on the front and one on the motherboard, There was no fans spinning nothing, O.K i tested power supply thats ok tested cpu thats ok tested motheboard no power to the pci or agp so i thought it was dead, I changed my motherboard for a new one and changed the cpu and power supply for new, the only bits i used from orginal pc was optical drives and harddrive, Tested pc everything fine for a few hours turned it off went to turn it back on found it totaly dead just like other pc, If someone can help solve this mystery i would be most grateful, Cheers
