doen't come with onboard video

...this is getting really annoying, i'm going to check the jumper settings on my MB just to make sure that its not set manually on the MB itself to use PCI...this is causing me a lot of distress, also my RAM may be the problem, does it make any difference in what slots you stick the sticks in? i have 2 sticks of 256 MB (and its Ultra, so its not a question aboot shoddy brands), my MB doesn't have the dual channel slots, so i don't think it should matter..does anyone know otherwise????
