I would suggest reverting to the previous video card driver and it will fix your problem. The new driver is what is causing the problem. I had the same problem for two days 5/14/09 and 5/15/09 till I found out that it was the driver.
thanks the igfx problem is fixed but now i notice my laptop locking up after use. i think it might have to do with the video card overheating the system but im not sure. any help on that situation would be helpful too.
