In the olden days, win98, etc. there was a dos format command  format/MBR.  I haven't done much work on xp or vista systems, you might want to do some investigation on the web to see how to wipe the MBR, or if it might cause the hd to become unusable.   I had done it on older operating systems to resolve problems.

Hi Richard

Thx for your help.

If I've done a full reformat, would that not delete the MBR?

I have a Paragon Rescue CD which purports to "fix" the MBR. I've just tried
that, but no difference.

Just to add to what I've already written, I've tried booting from an IDE
hard drive with XP installed (off another computer). That brings up the
boot options. When I select Safe Mode, the drivers load as far as the usual
Mup.sys and then the computer just reboots itself.

All fans are working, so it doesn't seem to be an overheating problem.

There are no POST beeps so I assume memory is OK.

Tried that, made no difference. Also tried another cable and power plug.
The CDROM is Sata. It's working. Does that tell us that the Sata Controller
on the mobo is OK? Or are there different controllers for the hard drive?

What next?
