Well i previously had 2x1gb Corsair XMS2 PC2-6400 Ram Sticks in there. so i bought another set of the same ram, and tried to put it in. A few times it would just freeze at the mobo splash screen, it never made it past that. Now when i try to boot i just get a black screen. Ive tried going back to just the old ram, then tried just the new ram. Then i cleared the CMOS and tried both again, and still just no video response at all. Any suggestions?
