Hello, I had this tablet for about 2 years, and everything has been working perfectly until a couple of days ago. When I turn on the tablet, 4 out of 5 times, I'll get a messed up looking display. The "HP" logo will be fragmented, in 3 pieces, nothing will look straight, I'll have broken text all over the place. After forcing the tablet off, and restarting a couple of times, it will finally load up normal. I am using Windows 7 64bit. Does anyone know if this is a driver problem?
