How to diagnose this one ?

Hi there,
OK, last weekend collected a PC from a customer who says it's powering down all on it's own and has finally corrupted the hard disk so it won't boot again.
I did the usual repair stuff and got the system up and running again. I suspected the power supply, cooling etc but all seem to be fine. Spent a day trying to get it to fail but nothing. Customer has had the PC back 5 days and is on his way round to drop it off as it has started happening again! ideas anyone ??
I've not tried a new psu, would this be worth a go, it's difficult though as getting it to shutdown seems so intermitant.
thanks simon
