Computer was running then screen went black. Shut down machine turned back on. Power going to machine (green light on at back and main power light on at front) but no fans turn.
Any clues on this?:confused:

seem like your PSu is giving up on you. do you have another you can try

PSU or motherboard in all liklihood. Take bobbyraw's advice and try another PSU first. Disconnect all drives and remove PCI cards while testing.

Inspect capacitors on motherboard for signs of swelling or leakage. Pay special attention to those around CPU socket.

Thanks Guys,

Motherboard needed replacing. Everything OK now.

Cheers,
