I was trying to overclock my processor and went a little too far and got a BSOD during Prime 95, I put settings back to they were that I know work, and when I got back into Windows 7 64-Bit everything was fine except my headphones and microphone were not working. They are separate things, not a mic-headset. The headphones are working fine with other music devices, I'm not sure what's wrong but it's frustrating since I go on skype a lot. I'm in the Recording tab in the Sound control panel and there is no noise being detected by the microphone. I've tried reinstalling the sound drivers but that didn't help. Any other ideas?
