Ok, I have had a slew of driver problems while getting my comp up and running with my new epox 8rda3i mobo.
for some reason, I had to put a PCI card in to load windows( the comp wouldn't even post, same thing happened on my Soyo dragon ultra) after windows was loaded, I took the pci card out(ATI 7500) and put in my FX 5900xt. I finally got the latest drivers installed (after much frustration) but I tried to play HW2 and it said my card was running in PCI mode. I go to the nvidia display options, and under the tab geforce 5900xt, in the adapter information it says: bus PCI x0
also, my card is on IRQ 19.
this has never happened to me before. If you guys need any other kind of Info, let me know.
here is a picture of what I am talking about
