Audio Hardware Problems

Hi, just a couple days ago i have to reinstall windows to my computer due to a system 32 file corruption. After i did so, the sound stopped working even after i reinstalled all the drivers and the driver for the sound card already in the computer. Currently i have audio codecs, creative game port, creative sb audigy 2 zs (WDM), legacy audio drivers, media control devices, and unimodem half-duplex audio device under my Sound, video and game controllers. I've searched and installed the latest driver on the internet for the audigy 2 zs as well. There is no sound coming from either my headset or speakers. Any tips or pointers would be greatly appreciated here.
Thanks.
