I suspect it was either faulty hardware or a corrupted
Windows installation.

In general I don't like to propose unspecific measures, but:

perhaps a first step could be to install Windows XP on a
second empty hard disk and see if the problem goes away. If
it does not then you can rule out a corrupted Windows
installation or a corrupted file system (as it was installed
on an empty harddisk).

Using this method you can return to your old Windows
installation without the need to reinstall applications,
etc. The second Windows installation can also be used as a
backup installation if the first one fails - this can be
very handy if you don't have time to fix the problem, but
just want keep on working. (I also use it to switch back and

Windows - although a virtual machine would probably be more
