Essence STX + 7950 = Buzz/Humming in mic? :(

[bzdsftw]

Hey guys I'm in need of some serious help. My setup is as follows:

Asrock pro3 z77 + i5 3570k @ 4.2ghz

MSI 7950 Twin Frozr @ 975/1500

Asus Xonar Essence STX

Corsair TX650M

Basically, I game with a HD 600 and an antlion modmic attached to it. This has not been a problem till now. I have been using the sound card since the start of April and have not had any problems with it till today. My problem is that whenever I play a game than puts my gpu under any sort of load at all, even League of Legends, my microphone starts making the crazzy humming and buzzing sounds that makes it sound like there is a chopper in the background. I have confirmed that the mic is not faulty by using it with the onboard realtek audio chip. Works without a problem. The humming only occurs when my gpu is under load. Mic works perfectly fine at desktop. The noise is incredibly annoying and all my friends are complaining on Skype. I've read up somewhere and have heard that this could be EMI? I have no knowledge on the subject. Also, before this happened, my house power went out and my computer shut off. Could that have damaged my sound card? I've been gaming and chatting before with the exact same setup with no problems.

check if mic boost is on or try installing the unified xonar driver.

Try moving the sound card to the furthest slot down.
