I think this has got to be down to the motherboard, there's nothing else I can think of. I can't explain why XP works on it and why 7 doesn't, but everything else has been ruled out.

Paul when you typed in list disk and hit enter what did it show as disk?
List the disk it showed if any.

What brand and model of ram do you have, frequency, voltage and timings and size modules

Try downloading peppermint Linux live DVD, it runs in ram and you don't even need a hard drive connected see if it runs OK. 1. Download and Install | Peppermint | The Linux Desktop OS It should be an ISO image and can be burned to a CD if lees than 700MB otherwise a dvd.

EDIT: I believe the 64 bit version is 576 MB. so a CD

Paul, you have apparently had this rig for some time, am I correct? if so, what ram have you been using up until recently?
