Firstly hey all, this is my first post on these forums What am i looking for...is an answer for my following question: Just bought a Gigabyte GA-965P-S3 rev 1.0 and a Gainward 7900GS. The system just won't post. I went to a friend, tried to boot with his x1900XTX or something like that ATi card...it all went all...also his MSI SLI mobo managed to post with my video card. Now, i am feeling i am watching a SF movie: all computer components work but not when assambled together. Do you have any ANY idea what could cause this? PS: Full sys spec: Gigabyte GA-965P-S3 rev 1.0 mobo, 2x1gb ADATA ddr2 667, Gainward 7900GS video card, Spire 500W PSU. Nothing else connected to the mobo atm.
