After upgrade to Vista, my laptop just stating behaving improperly. With XP things went fine, but a friend suggested me to go for Vista. After upgrade the automatic drive detection wizard failed to install a number of different hardware. Like the webcam, the audio drive, lan, etc. Nothing is working. The webcam is installed but it disconnect on its own after a few minutes. It is not constant. The same thing is applicable for the audio device also. My resolution is also affected a lot.
