I've an HP Envy Touchsmart, and noticed this has happened three times since I've had the machine just over two weeks.
I've bought it out of sleep and the screen is shaking so bad, that I cannot get the mouse on the program hardly, and when I do, it won't close down the programs. I've managed to close them down through the Taskmanager but even that's hard to work with when the programs seem to be blended together and shaking.
Any idea as to what is taking place here and is there an easy fix.
