Ok, i bought a new computer completely from asus. This motherboard has no inboard video card. When i put an AGP card in it does nothing but beep and refuse to do anything else when started. When there's an PCI card, it dosen't beep, but i don't get any video signal. Anyone have any ideas.

Make a note of your BIOS version then find a BIOS beep code chart for it. Listen to the beeps you get with the AGP card in and find the error it corresponds to.
