After installing vista i noticed only 2 problems. All sound played on it skips. When im listening to music, it gets "hiccups", and is a little distorted. It skips or something. Im guessing this is a driver issue? What could it be? Where could I get the driver, Ive been looking. My speakers Conexant AC Link... I also noticed the screen just goes black when im trying to shut down, and nothing happens.... Well it starts to but then on the final step it seems to not actualy turn off... Please help...
