I have a Asus k8v se deluxe motherboard with a amd 3700 64 bit 754 socket processor. When putting in ati radeon 9800 pro 256 mb card, the screen stays blanks and nothing boots. I have 2 separate k8v motherboards and this happens with both, but when I use the card in my older soyo motherboard it works just fine, so I know its not a problem with the card being broke. All other video cards I have work in this motherboard with no problem. I have read somewhere that the 9800 pro has problems with some power supplys, so i tried a couple different and the same thing happens with all of them when trying to boot it with the k8v motherboard. All power supplys I tested work with the card in my older soyo motherboard, and nothing seems to work with my asus. That is why I am starting to suspect its a compatibility issue with this certain motherboard. Just wondering is there is anything i can do or any reason why this card will not work with this motherboard. Thank you for your time.
