please unisntall and reinstall all your drivers for your sound card

Make sure you have the latest drivers as well as BIOS.

In Safe Mode I'd run AdAware and Spybot Search and destroy and I would also clear the CMOS since you're using onboard sound.

The instructions to clear the CMOS will be either in your motherboard manual or in the manual you got with the computer if you didn't build it yourself. If you don't have the manual, should be on the mfg website. It just involves moving a little piece of plastic covering little pins on your mobo. The pins are usually near the battery.

what do you mean ed?
