No moniter, but boots into Windows

I can get to Win with the on-board, but when I disable the on-board and set video to AGP, I get no moniter ,but it still boots into Win. I have all of my extra cards out now, to no avail. All I did was change my modem to a different slot, now I get this. I have tried 2 different vid cards and 3 moniters that all work fine on my other rig. What else can I try before I assume my AGP slot died?

Hmmm that is strange... I would have thought that if the AGP slot is dead, the mobo would detect no video and not boot up but give a POST code instead...sounds like your motherboard is having "difficulties". You might just want to get a new one!

I was thinking that myself. The prob is that I will have to wait around a month if I RMA it. ASUS has poor support. Sigh.
