PC stopped working

I have a tower PC which has stopped working. Have tried different power supplies (two others) and no joy. The lights are lit on the on/off button but nothing is happening. The heat-sink fan doesn't spin, neither does the one serving the power supply. Can anyone point me in the right direction of what I should check next. Have a multimeter at my disposal. Thanks
 
Is this a custom built PC or store bought? Recently built? My guess is that the motherboard is shorted against the case possibly. Were the brass standoff's used betweent he motherboard and case?
 
Is the wire for the switch connected properly to the board?

When the large P1 is plugged into the board from the PSU does the green light (assuming the board has a green light) come on?
 
PC defunct

Thanks guys.
It is a package that I bought through the internet quite a while ago and had no problems for years. I'll check if the motherboard is shorting. Not sure if they used brass standoffs. I'll check that too.
I've disconnected the main switch and reconected it to the board, using the correct pins. Not sure if the board has a green light. I'll check that too.

Going on hols tomoz for two weeks so if I don't reply to further messages I will do when I get back.

Cheers

If you've used it for years, then it's pretty unlikely that the motherboard is shorting against the case. I'd say the most likely culprit is bad capacitors on the motherboard. Often you can visibly tell if they're bad, as they will be bloated and/or show signs of leaking fluid. You can replace the motherboard, but for an older computer it might be wiser to buy new.
 
Can't see anything untoward on the motherboard like burnt out components, dry joints or burnt out track. Just wondered whether there was a simple pin-out way of checking the motherboard.
 
I had the same problem and i discovered the problem was the mainboard due a electric power outgage.Also,the processor was affected.
