What seems to be the problem of you jumper settings?
JP1 PIN 1-2 = On board audio disable
JP1 PIN 2-3 = On board audio enable
JP2 = Temperature Sense connector
JP3 PIN 1-2 = Normal
JP3 PIN 2-3 = Clear CMOS
1. Power off the system and unplug the chassis AC power cord.
2. Short JP3 at PIN 2-3 for a few seconds.
3. Set JP3 back to it's normal position at pin 1-2.
4. Plug the AC power cord to the chassis.
5. Power on the system and load the BIOS setup default.
