Full screen videos keep restoring down, Graphics card problems?

Hey first off your laptop should be able to run full screen videos fine. However I can tell you from experience the whole video card problem is not just you. I have an HDX18 that I put win7 on and started getting the bluescreen everyday (and still am). I also got the same type of bugcheck and what not. I have an nvidia card so I have a feeling it's something to do with going from vista to win7 or HP's drivers. Also check when your videoo card was last updated, see that's about when the problem started. I'm using a 1 1/2 year old driver on mine which has helped a little. I've researched a ton and still nothing yet. Good Luck. Also run a full virus scan if you haven't lately.
