About every 4 years, I build a new office system. This time, I selected a P4P800-E Deluxe MB and ATI AIW9600 AGP card. The hardware assembly is completed, but when I power on to try to set up the BIOS, the monitor displays "Please check the signal cable," signifying that it is not getting a video signal.
Here's the weird thing: I have a working system with an Asus A7V266-E MB and ATI Rage 128 Pro AGP card, but I get no video from the Rage card when I install it in the P4P motherboard. I also get no video when I install the AIW9600 card in the A7V system. The truth table reads like this:
P4P + AIW = no video
P4P + Rage = no video
A7V + AIW = no video
A7V + Rage = video
Ordinarily the no video condition from the AIW in both MB's would cause me to suspect the AGP card, but I can't figure out why I can't get video from the Rage card in the P4P MB, and I can in the A7V. Both AGP cards are supposedly compatible with a 1.5V supply, and both MB's supposedly supply 1.5V to the AGP slot. I realize I have a lot of variables to check, but for this forum, I'm interested only in known motherboard problems. Have any other hardware geeks out there experienced a similar problem with no video output from various AGP cards in this MB, and do you have any insights into what might be causing it?
