Ahhh, I do know a little about this one. Check out my post here: http://techreport.com/forums/viewtopic.php?t=18641&highlight=
I had a similar problem awhile back with my wifes laptop. But, if it is brand new, I would RMA it (send it back). Could be that you have a bad LCD convertor, processor is too hot, or your RAM is on the fritz. I would definitely send it back if it has only been a week or so since you bought it.
