No Signal at first; 1-3 reboots later, I get a signal

I recently built a computer with the following parts:
CPU: Core i5-4690k
Motherboard: Gigabyte GA-Z97X-UD3H ATX
RAM: Corsair 16gb 2x8 DDR3 1600
SSD: Samsung 120 GB 850 EVO SSD (OS boots from here)
HDD: WD 1 TB Caviar Black HDD
Power Supply: Supernova 750G2 80G PSU
Optical Drive: LG 24x DVD burner
OS: Win 7 Pro 64bit
CPU Cooling: Corsair H55 Liquid cooling kit
Case: NZXT Phantom 410

Display: Acer G276HL Gbmid 27-inch (1920 x 1080)

I spent a weekend getting it setup. I'm not a newbie, but not an expert either - somewhere in between. While building it, I had no issues at all with "no signal" to the monitor, but I was using a totally different display while setting it up which makes me suspicious of the monitor I'm using now.

The Problem:
When I start it up fresh in the morning, it usually takes between 1 to 3 reboots before the monitor will finally get a signal and display the mobo load screen. Either that or I just press the reset button and it sends a signal to the monitor. This didn't happen while I was building it and constantly restarting for windows updates. But I was using a different monitor while I was building it and it was plugged in with DVI not HDMI.

What I've Done:
-24-pin and 8-pin power plugged in
-GPU power plugged in
-all case fans plugged in (2 exhaust, 1 intake)
-all hardware is seated properly and all necessary cables are plugged in, including all front panel cables
-proper number of standoffs on motherboard
-I/O shielding installed
-CPU cooler firmly in place with thermal paste
-All drivers are up to date (358.91 for the GPU) for motherboard, gpu, and all peripherals
-Ran all the windows updates
-ran CCleaner and virus scans.

Everything else is running smoothly and there are no other issues with the computer except for this problem. I even followed this guide on setting up my SSD:

Help would be greatly appreciated. Anybody run across this before?

Strange advice: try to reseat memory modules, even if they are properly plugged in.

I lived through a stranger situation: The computer were opening, i heard the windows sounds, i could shut down with alt+f4 or play the music file on the desktop but there's no display on the monitor. After trying several restarts i was able to make screen display. I tried several things-first suspects were video card and monitor cable, i tried with another ones-but nothing worked. Than i tried to reseating memory modules(on the same slots). It magically solved my problem. I was sure memory modules were seated correctly. But somehow they needed to be resetaed.
