Newly built desktop POSTs but does not display on monitor

Hello there! Thanks for taking a look at my problem, I'm hoping for some direction. I have just built my first desk top using parts from Newegg. The problem I'm having is that the monitor does not appear to be picking anything up.

The hardware: http://secure.newegg.com/WishList/PublicWishDetail.aspx...

I used the parts on that list, but reproduced here
Motherboard: Intel BOXDH77EB
Processor: Intel core i3-3220 Ivy bridge
Videocard: Geforce GTX 650 Ti
I think are the important ones.

Order of events: When I power on the tower all the fans (case, videocard and processor heat sink) turn on, as well as an LED on the case and an LED on the motherboard. There is a single beep from the motherboard and then just the fans. At no point does the monitor display anything aside from a notice to check the signal cable.. I have tried hooking the monitors DVI port to both the motherboards HDMI port and the videocards DVI port with no change in symptoms. I believe the monitor is working because when I plugged the HDMI side of the DVI-HDMI cable into my laptop it functioned immediately.

I have tried calling Intel's tech support. They had me remove the RAM and power on. Still no display but the motherboard beeped three times in a row (which is the memory error code). It was at this point they realised I had a connected video card and told me that I would not be able to get a display by connecting to the motherboard while it was still installed, and that connecting directly to the video card should resolve the issue (I did not have a regular DVI-DVI cable and had to go to radio shack for one). It has not.

At this point I'm not sure what I need to do, or try, or how to test components. I'm a little intimidated by the prospect of removing the video card, I tried following the instructions and pushing down on the level but to no avail. I did remove the screws holding the card in place.

Thanks for your time.


UPDATE: Ok, I manned up and removed the video card. Turns out that by poking in from the outside of the case it comes out pretty nicely. I then tried plugging the monitor into the HDMI and DVI on the motherboard and powering on. Still no dice.

I have also removed the heat sink to check that the cpu was seated properly. It appears so. I'm just going to put the heat sink back on for now without applying any thermal compound (the heat sink came with some pre-applied and it is currently still on the heat sink and the chip).

UPDATE THE SECOND: Machine appears to post normally (this has not changed) although I have noticed that when the monitor is plugged into the video card through DVI, and is on the correct setting, the screen is simply black. No check signal cable message, no weird dark-powered-on light. Just a matte black.

It's fairly easy to remove a video card, especially if you said you assembled the PC yourself, the video card is one of the easiest part to replace.

But anyways, I wouldn't remove it right away. Did you make sure your monitor was set to the right input? (Which is DVI I believe you're using right now?). Because if you connected your laptop with HDMI, you need to switch the input of the monitor to DVI if that's the port you're using for the PC.

Also, what other output ports do you have on your card? You could try with HDMI instead. If your card has no HDMI port you probably have a displayport so you could try with a displayport-to-HDMI adapter or a displayport-to-DVI adapter and see if it works. And always remember to set the monitor to the right input when you change cable.

I toggled through the inputs each time I tried a new cord/port combo.

The ports on the card are two DVI, and one mini HDMI which I do not own a cable for.

At this point I did not get a display when it was only the motherboard (no videocard installed.

Shot in the dark: New MB have a BIOS setting to select which output for video. I.E= If you had a dedicated card(650) and for some crazy reason you wanted to use the on-board ivy you can switch between them.

Good luck finding the setting, Remove the 650 when trying the on board and try it in both positions see what ya get.

I understand you tried both outputs so one should have worked again shot in the dark.

I've tried both with and without the video card. I can hear the poor thing post, but there is nothing showing up on the screen. The only two things I can try now are the mini HDMI port on the video card and the display port on the motherboard, but I don't own cables for either of those.

Additionally, because the machine isn't displaying anything to the monitor, I can't mess with any BIOS settings.
