Is this the stock drivers?
And which dv4? I see 30 or more models at hp.com.

HP Pavill dv4 Vista, screen jumping every 2-3 seconds lasting a second, does it much worse after it goes to sleep for a few minutes then calms down to a steady 2-3 seconds before next hiccup. Also very bottom of screen constantly jumping, unreadable bar, can see some of the icons from very top of screen down at very bottom. Any advice really appreciated driving me nuts hard to work.
