It smelt of burning whilst I was operating it, so I quickly went to shut down, but before I did, it powered itself off. I opened it up immediately and the inside was extremely hot. After an hour or so, I plugged it back in.
None of the fans in the power supply worked. The fan on the motherboard itself gave one turn and stopped, followed by a constant orange light on the motherboard. I don't know about the front-panel lights since they haven't been re-connected since I had the computer repaired a year ago. None of the components look "bulging" or discoloured. There isn't an awful lot of dust present, although I guess it could do with a clean. I've had motherboard failure in the past, but at least then the power supply started.
All is under surge protection. The PSU is a 400W and the motherboard I think is an AGP/ 8X.
