Onboard Audio decided to hate my headset....HELP

Ok, so I was playing WC3 when someone knocked at my door. So I left my Logitech Precision PC Gaming Headset on my desk, when I returned I put them back on and there was no sound, so look at all my connections and headphones but there's no problem... I go to Realtek control panel and Audio I/O and everything is correct....but when I test sound, tests left ear then right ear, I could hear it in both ears rather than one side then the other. I can hear background noises of games/windows sounds...but nothing else. I don't know what happened.... Any ideas?

I thought it was my headphones but I plugged it in on my other computer and it works 100% fine..

Update: I just tested ipod headphones and the balance works... but my main headphones still have select sounds playing on both speakers...

Update 2: My headphones are a Headset/Mic combo..so it splits into a Green/Pink... When the Audio is plugged in without the Microphone it works, but when the microphone is connect along with audio it doesn't work.. I have tested this again on my other computer and it works fine with them both plugged in.
