Hi all, I'm after the wise wisdom of the tech heads on here. Yesterday my son said his PC started turning off, and when he tried to turn it on it would switch off again. Then he said it wont turn on at all. I looked at it and the side case fan was clogged with fluff so I cleaned it out and I also took off the heat sink fan and cleaned that out. Put it all back together and nothing. There is residual current because all the mother board lights etc are on, but when you turn on the side case fan light comes on and it starts to turn then 1 second later it all stops. Could it be the PSU (power unit) that's buggered.
Any ideas?
