[Magdalen] Dreaded Screen.

[Jim Guthrie]

This often represents an occasional conflict between an old driver and
Microsoft's most recent updates. And it will only kick in when you've done a
succession of different things that will trigger the driver to be in memory to
make this happen.

It can also mean a bit of bad hard-disk. Have you run Chkdsk .F lately? After
that, Defrag if you don’t already do it regularly.

And of course, you back up everything regularly, so do all this immediately
after a full backup.

Cheers,
Jim
