I have this friend (no really!), and his computer has stopped working. He could smell something burnt one day and it stopped booting. I've had a look at it, lights are going but no fans or anything. The motherboard looks fine.
There is a light on the side of the powerunit that is not going, it says 'test switch' next to it. So I gathered it was probably the powerunit that has gone bust, but I wanted to ask some more proficient people before continuing.
The computer is a Gateway P4.
Any thoughts would be much appreciated.
