Re: My PC has stopped working
Make sure the motherboard isnt shorting out on the case, specifically where the ide channels are on the board, this could be the cause of the intermittence, and like hasbeen said try memtest.
I once had a virus that disabled my cdrom drive on startup, so maybe check for viruses (outside chance)
