sli'd 7900gts help
i got two evga 7900gt's, and i can't manage to run them in sli. i install them both in their proper slots, put on the bridge, put power in them, turn on the pc. everything goes swell until after the windows progress bar ends, the screen just goes black and the monitor button goes yellow, which is idle. what am i doing wrong? i have a evga matx nf44 mobo, along with two 36 raptors in raid 0, along w/ 2 gigs of corsair ram, amd x2 4200, dual vf700s on both 7900gts, and a dvd burner. plz help!
