Ofcourse thier not working after reformating you have to d/l EVERY SINGLE DRIVER that you had before. The problem is that you reformated BEFORE BACKING UP YOUR DRIVERS. Right click on my computer and go to device manager. Ok now if you see any yellow exclamation marks. Its because the hardware cannot work because you dont have the drivers to run it. Find out what kind of sound card you have. Then go to the company's website to d/l drivers for it. It depends on your motherboard. If your motherboard came with an integrated sound card. That means you'll have to find out what kind of motherboard you got and what type of model it is. Then go to the mother board's company website and d/l thier drivers for the exact same model you have. If not then all you have to do is find out what kind of sound card you have. Then go from there.
