I have HP pavilion 2500 (dv2945se) os Vista premium. I recently installed win8 and everything is quite fine but the hidden bars on the right and left have problems to appear when I approach the corners. So I can't shot down nor can I have access to mail, weather etc., but I car run the other programs. When I disable the VGA, the standard VGA is replaced by windows and everything is OK. So I think it's the VGA driver. What can I do for that. The updater can't find any better driver.
