Onboard video problem

I just finished a new build and am having issues with getting the onboard video to send any signal to my monitor. I've built my fair share of pc's in the past, so I'd like to think I'm relatively familiar with things, although it's been 6-7 years since my last build and some things have changed slightly so I could be overlooking something I suppose. Anyhow, I'm using an i5-4670k, Asus Z87 Pro, 8GB (2 x 4GB) GSKILL Sniper 1866, a Crucial m500 240gb, and a Fractal R4 case.

When I added in an old discrete graphics card (sadly, an old GeForce 9600 GT), it boots up just fine with no problems at all. If I connect using the DVI on my monitor to the onboard ports, nothing happens when I boot other than the case apparently turning on normally, just with no monitor signal. It strangely seems that my case doesn't have an onboard speaker as far as I can tell to give any beep codes, unless I'm overlooking the speaker and wire somewhere...so I'm not getting any beep codes. It looks to get stuck saying A0 on the motherboard LED when connected to onboard, which strangely looks to be the same thing that happens when I successfully boot using a discrete card. I believe the onboard video is showing up in the BIOS since I can enable multiple monitors and select IGPU in a couple of the menus. The HD 4600 only shows up in Windows if I have multiple monitors enabled, which I assume is likely automatically disabled by default when a discrete card is detected.

I've tried most everything I can think of with my current equipment. I've disconnected everything except a single stick of RAM from the board (no HDD or anything else) and tried booting up with the same results. I've checked for bent pins in the CPU socket and reseated the CPU and put new paste/grease....same result. Can anyone think of something simple I may be overlooking? I know the BIOS is a little different than I'm used to, so is there somewhere I'm not seeing where the IGPU has to be enabled that might not be worded in a very obvious way? The only other things I can think of to try is to get an adapter to try plugging into the HDMI/VGA slots to see if the result is the same, but I don't have either currently.

I guess I should have been more specific. Any time I've tried the onboard video, I have removed the dedicated graphics card first as I assume that automatically disabled the integrated graphics.

About the only thing I can think of trying that I haven't is getting a different type of connection to plug in (which I don't currently have, other than HDMI...which I guess I'll try here shortly). My monitor is pretty old and uses a DVI-D(single link) connection.....I'm not sure if there's any compatibility issues between that type of a connection and the onboard HD4600 GPU.....I've tried Googling for any information on it and haven't come up with anything to suggest that'd be the case really....so I'm grasping at straws here.

Well...a bit of an update. I pulled one of my TV's into the same room and connected the TV's hdmi into my back display port panel and I have it working in dual monitor mode....so the onboard video appears to definitely function. I'm not sure if it'll boot with just that plugged in, but I did try a 2nd DVI monitor to enter dual monitor mode and it flat out did nothing. I'm rather confused about what the issue is, but it does appear to be directly related to the DVI.

Well, I've got it working on my monitor now. It will boot up to my TV from the onboard (ie. with the discrete card physically removed) using HDMI or the display port to HDMI adapter. I managed to find an old male to male VGA cable and it turns out that will boot up fine now too to my actual monitor that I've been trying to get to work using that cable instead of DVI. Essentially, it seems like everything works fine other than the DVI port for booting up and it doesn't detect any errors when I try to boot up to the DVI (the monitor just never receives a signal, otherwise the PC acts like it's actually booting up....I just can't see it) so it's a bit strange. I was going to try to use a dvi to vga adapter to see if that'd boot up, but my adapter is a DVI-I and doesn't fit into the back I/O DVI port. I'm honestly at a complete loss as for any explanation as to why that specific port won't boot up.
