First time building a computer, no signal

[khorik]

Hello, I finally finished putting together my first PC, and this is the first hiccup I've run into. Everything in my computer seems to be plugged in fine, and when I tried test running my comp before I closed my case and plugged in my monitor, everything seemed to work: my CPU fans spun, my MOBO lights lit up, all my LED lights lit up, my graphics card's fans spun, and my HDD whirred. Now, when I plugged in my monitor, I was extremely disappointed to see the "No Signal" on it.

I don't have a MOBO speaker so I didn't hear any kinds of beeping. I'm not really sure what I'm doing wrong.

Here are my specs:
CPU - Intel Core i7-4770K 3.5GHz Quad-Core Processor
MOBO - Asus Z87-PLUS ATX LGA1150 Motherboard
Memory - Kingston Predator Series 8GB (2 x 4GB) DDR3-2133 Memory
Storage - Samsung 840 Series 120GB 2.5" Solid State Disk
Storage - Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Video Card - Gigabyte GeForce GTX 770 2GB Video Card
PSU - Corsair Enthusiast 850W 80+ Bronze Certified Semi-Modular ATX Power Supply

Here is a picture of the top half of my MOBO when it's turned on (sorry about the bad quality):

Hi, here's an update.

I've tried taking my GFX card out to use the MB video output, but it still says no signal. I read that a lot of people had trouble with their RAM not being in but mine is clicked successfully in place. I pushed down on the sticks a couple extra times just to make sure. Also, on my MB, only my DRAM_LED and my power button are lighting up. I have a VGA_LED on it but it's off. MY CPU_LED flashes once when I first turn on my computer but that's it.

I also tried updating my BIOS by by putting the Z87PL.cap that was on my Asus support CD onto a flashdrive and plugging it in. I pressed the Bios flashback button for about 4 seconds (the manual says to do it for about 3 seconds), but I'm not sure if it actually worked. Nothing flashed or anything so I have no clue.

Someone please help me!!!
