I recently had a problem with a spyware program or virus or something that removed my wsaupdater entry and windows XP would not allow me to log on. Through console recovery I was able to fix the problem. Before I had the problem my system worked fine including my sound card. Since then, my sound card does not work. I got an error message that the "file format was not supported" when I tried to launch MusicMatch to play a sound. The onboard sound is disabled, the device manager does not show that anything is wrong, it says that it is working properly. Any ideas would be appreciated!
