I've seen similar symptoms on overheating 5150s. Those were the subject of
a lawsuit (see
www.lundellsettlement.com). I suspect that's what you've
got, but you could try temporarily turning down the thermostat in the office
to verify for yourself that overheating is the problem. If it is, I don't
know that there are any really satisfactory remedies. (All the lawsuit did
was force Dell to extend the warranty a little longer for this model. It
didn't really fix the problem.)
