I was not getting a posting beep, and returned the mobo. Now it is not recognizing the AGP ? Video card. I tried 2 cards, and at one time the lesser board was recognized, and when I switch to the better board, both don'twork. The boards are good as I took them from systems that were operational. My question is is it possible to do something to make them connect. I hate to rma again. I did put an eraser to the contacts.Case has 320W power, Athlon XP 1600, 256k Muskin DDR memory. The only board installed and is a modem. It does post with that board installed. I took the board out of the case, and installed the system one screw at a time and checked to see if it posted. It did not post only with the AGP card.
