My laptop is hp probook 4730s. I downloaded all drivers for Windows 7 x64 from hp site. The problem is with video drivers. To get hd3000 (intel) to work I need to get drivers from intel only, that's all right. I have tryed many different drivers (signed and not) from hp and ati and all give me non -workable results. In some cases I get black screen after windows 7 boot logo, sometimes white line blinks, and sometimes I get to windows and in task manager I get error: Windows has stopped this device because it has reported problems. (Code 43). If I get run CCC I dont have any configurations there. What could it be?
