Do you have a separate graphics card? If not, or if it works in a different system, then try resetting the CMOS, then using a graphics card instead of the integrated graphics (assuming you can get a graphics card that will fit easily) and if that doesn't work, first try with the motherboard out of the case, then try replacing the motherboard (you most likely can't fix it, and an AGP graphics card would be hard to find even if that is the problem). If the graphics card (if it exists) doesn't work, then replace it.
