I have an HP Pavilion A730N that is no longer displaying anything to the HP 1703 monitor hooked to it. I removed the monitor and cable and hooked it up to my company work laptop and it displayed images fine. I'm thinking that the VGA portion of my motherboard is bad. From what I can find, I have an ASUS ptgd1 la motherboard. If the monitor and cable are fine, where can I find a new motherboard. I can find used ones on various websites but I don't want a used one. And I don't want to buy a new one from overseas. Any assistance would be appreciated.
I'm running Windows XP and no matter how many times I boot the computer, no signal is received by the monitor.
