im not a tech savy person in the first place, but i upgraded to windows 7 and now its saying no audio devices are found. i believe i have an hp pavillion dv6-2066dx, but other than that i dont know much about it. also it says i dont have the authority to do system restores or even fully download anything. so im not sure whats wrong. sorry if this has been asked a million times but i really need help =(
