ah, alliance...Im sorry, I cant help you! j/k
that game is totally addicting. its trashed my sleep schedule, kept me from doing my dishes etc. oh but its fun!
the agp is connected to the PCI bus through a bridge basically, so I wouldnt worry about that. I will double check that on my machines when I get home (at work right now, onboard video-yuck).
Im still thinking display driver from asus for your mobo. after that, can you try that card out in another machine? maybe a friend can let you test it out in their machine.
that voltage # is high, for a 4x/8x card, hopefully it hasnt damaged the card by over juicing it for so long.
if the display driver doenst work, I am starting to think its a bad card or agp slot, but cant say for sure yet.
