Have you tried plugging the monitor into the onboard video. If it works you will need to let bios know you have an agp card or make a jumper setting on the motherboard. If it does not work reseat the video card and try again. If that does not work, borrow another known working video card to see if that works. Hope this helps.
Sadly there is no Onboard Video card on it.
Secondly, I searched the manual..but there does not seem to be any jumper settings for the Video card on it.
I don't know how to reset the video card....can u help?
thanks for ure effort.
