Hey guys/girls well i recently reformatted. Everything was working fine but then i open windows media player 11, all of a sudden my speakers start screeching and my pc runs really really slow like 0.1fps. It does this whenever i open any media file videos,music i tryed using different programs e.g. Winamp but i had the same problem. Ive tested the speakers on a friends computer and they work perfect. Also i have an xbox 360 and if i connect to the internetthen open a music/video player it disconnects my internet, I replaced/update the correct drivers (Realtek AC97) but the problem still exists. Please help, Thanks
