COD4 MULTIPLAYER WONT STARTUP Tags: PC gaming Multiplayer Gigabyte Video Games Last response: November 7, 2012 11:45 PM in Video Games Share ahmedkhan94 November 7, 2012 10:58:38 PM so recently a month back i built a pc and bought cod4, it worked perfectly until my pc wouldnt start one day and i sent all parts back to replace. the only thing i cahnged was the gpu from gigabyte 7870 to a gigabyte 7950 and the case from an apevie junior g to a zalman z9 plus. now i have the steam version of cod4. the singleplayer starts perfectly but whenever i try starting multiplayer it say. "iw3mp.exe has stopped working" i read online and some people told me to goto sounds-> recording-> and enable stereo mix (after checking the mark to show hidden devices) but the problem is i cant find stereo mix there.
