Alright, I have troubleshooted my whole new build because I was not getting signal to the monitor. This is the first boot of the system and I narrowed it down to the graphics card. The screen turns on when I have everything in except for the graphics cards. Could this be because I need to first go into bios and set it to look for a PCI graphics card? Or could it be that the graphics card is bad? I dont have the monitor plugged into the graphics card, I have the NGA cable plugged into the motherboard so I dont understand how it could be the graphics card stopping it from getting signal?

I've never had to go into BIOS to tell the BIOS to use the discrete video card, every motherboard I've ever used has been smart enough to switch to the discrete video card automatically.

I would guess that it's either a power supply problem (bad PSU or not enough watts) or the video card is bad. Have you plugged all the necessary auxiliary power cables into the video card?

What you did - connect monitor to mobo's video output port to start - is right. Even when you mount your own additional graphics card in PCI slots, the default setting of the mobo usually is to use the on-board video chip for output. You have to go into BIOS Setup and change that setting to get it to output via the add-on vid card.

HOWEVER, the fact that it works with no vid card present, and does not work work with it (them) installed, could have two types of causes. One is that the BIOS is smart enough to detect the add-on cards and switch to using them. If that were the case, then connecting your monitor to the output port of the added card will solve the problem. If that does not work, I'd start looking closely at power issues for the added vid card(s). If it (they) are not connected properly to required power sources, OR if it (they) are faulty, OR if your PSU is too weak to supply the power it (they) requires, that might cause the failure to boot and display properly.
