I just bought and BFG 8800 GTS 512mb to upgrade mi 7600 gs, the problem is that when I put the 8800 in my system it all works fine, but I realiazed that my dvd optical drive didnt work! It only reads CD`s but not DVD`s, so I put back my 7600 gs an the dvd worked just fine, reads CD and DVD ... what is the problem?? I think is because of the 6 pin conector or some cable =S ..well I dont know! please help me!
