Make sure there is a full and complete backup of important data. Download
a drive diagnostic utility from the hard drive manufacturer's web site.
That will create a bootable floppy or CD. Boot from that and run the
diagnostics.

To cut a long story short, I recovered the PC to XP service pack1,
factory settings. It meant I lost a bit of data, but had most of it
backed up.
After a few cold boots, it seems to be fine again. Service Pack 2
must have been messing with it, or over time had corrupted some system
files (i dunno). I'll try and install SP2 again, this time from
standalone, rather than Windows Update!
Thanks for the help.
