hi i'm not sure if its a mobo or windows 7 fault but my sound keeps getting turned down randomly if i set it at 100% little later it will be at 67% then lower and lower till its off completely.
ive tried all the fixes i can find around the net ie reinstall keyboard/mouse/realtek drivers ima using the asrock extreme 4 z77 mobo and windows 7 64bit its really annoying just started happening a week ago
