In the last couple days the sound on my computer has been acting very strange. I will be listening to music and all the sudden it will just start getting exetremely distorted and skipping. and sometimes it will just stop playing all together. I will click on a song and the time meter wont even start moving. I updated the sound driver, same thing. I tried using windows media player just to see if it was itunes messing up, and same thing. The only thing ive done differently to this computer is over clock the graphics card, which...i dont entirely understand what effect that would have. Sometimes if i restart the computer it will be good again but will only last so long. Any suggestions?
