i'm sorry if this question is inappropriate in this thread. i got my dfi 790fx dk m2rs board a few days ago. i finally got a chance to fire it up. i'm in the process of testing stability. i can't help, but notice this high pitch sound coming from the pc. anyone have this problem with this board? is there a fix? the sound is deafening and i'm thinking of an rma to newegg. please help.
