Crazythaij, I can't tell about the update, haven't noticed any. If reinstalling Windows did not fix it, that's kind of bad news as it probably means it's a mainboard failure, something that has been suggested to other people with the same problem. If you had the problem immediately after a fresh installation of Windows (without updates) it's most likely the hardware. In your case it can be the sound card, if you haven't tried another one.

Sgt_Grim_Reaper, thanks for the reply. I already tried reinstalling the drivers, several times. The Audigy software does have sound effects available but I made sure they're not active. Same for the onboard card.
