Hey guys.. I got a new pc and I think the mother baord is clashing with my graphics card. I really don't know what to do and could really help. My system specs are: ECS P4M800PRO-M 2.8Ghz Intel Celeron 1GB DDR 400 ram 160GB seagate IDE 40GB MAXTOR IDE G-force 5900 XT What it does is I have the card plugged in to my pc. but if I plug my screen into it, it doesn't work.. the screen just stays off. but when I plug it into my onboard Graphics it works. The only problem is My system doesn't find my graphics card at all. I have tested it on my other pc and it works perfectly. What should I do?
