Been using G55VW for a couple month without problem. Suddenly yesterday when I was playing game then the subwoofer suddenly stops....when I test the speaker, there is sound in Volume Mixer (the green wave), its just the sound in the subwoofer wont came out...I tried reinstall and install new driver...still no sound... tried take out my speaker out too...take it off and put it in back...same thing...just scared the subwoofer dead >.<"
