Hi etbsb

I think this is a pending hardware failure related issue.

I have an Inspiron 8200, 
with a Radeon Mobility M9, (RV250)
but running XP pro only.

I have the exact same issue as shown in your screenies,
which started occuring for me about 4 weeks ago,
following a major thermal excursion, (fans were accidentally disabled).

Googling
http://www.google.co.uk/search?hl=en&safe=off&newwindow=1&q=lcd+corruption&btnG=Search&meta=
brings up similar screenies, going back several years.

Seemingly it can be due to a -
- faulty/dislodged connector,
- laptop lid-closed switch
- failing vram
- etc.

In my case, 
mouse/keyboard activity can suppress the corruption.
