This is not strictly speaking a dead machine problem but somebody might have come across the problem. When I power on my PC (ShuttleX), the usb lights come on (mouse, hub etc) but nothing happens for about 5-10 mins and then everything starts up and boots normally. I've checked cables, run CHKDSK etc.
The only suspicion I have is that the clock is never right when Windows finally arrives which has not been fixed by changing the motherboard battery. Is this a BIOS problem?
