Hello! Completely clueless noob here, seeking your collective advice in (of course) dire straits!

I put together my all-new desktop computer using exactly the following parts list:

Processor: Intel Pentium G4400 (Skylake) 3.3 GHz
Motherboard: MSI Gaming Intel Skylake H110M Gaming
PSU: EVGA 500 W1 80+ WHITE 500W w/ 3 Year Warranty
RAM: Crucial 8GB DDR4-2122 UDIMM Unbuffered 288-Pin Desktop Memory
Hard Drive: WD Blue 250GB SATA 6Gb/s 2.5 Inch
Network Adapter: ASUS 802.11 ac Wireless-AC1200 Bluetooth 4.0 PCI-e /mPCI-e Adapter
Case: BitFenix Prodigy Micro ATX/Mini ITX Case

In case anyone thinks I forgot, there is, in fact, no Graphics Card in the system for now. I will receive my 1050 Ti from Amazon today, but I figured I would just build the system preemptively, get it up and running, and put the card in upon its arrival.

At any rate, I put it all together yesterday. Though I am anything but omniscient, this isn't my first rodeo, so I handled my parts gingerly, with the respect owed to expensive pieces of silicon, I made sure my workspace was clean and that I was grounded (I have an antistatic wrist strap). Anyways, I assembled the parts into the case without any noteworthy difficulty. I moved the case over to my monitor and hooked it up to the HDMI port on the motherboard (recall that I'm using my Pentium's iGPU for now).

Upon clicking the case power button, the computer apparently whirs to life, with the Mobo lighting up, the two case fans and HSF starting as well... but to my dismay, there is no video output whatsoever :( I attempt to use DVI instead just for good measure but nothing happens. I discover that once the computer is turned on, it only shuts off if I:
a) Hold the power button for 4-5 seconds
OR
b) Simply flip the switch on the power supply or unplug it from the wall socket.

I checked the Motherboard while it was running, and I got my first (maybe only) "Clue": There's a small panel of LEDs on the board, which many of you are probably familiar with, labeled, "EZ Debug", with a light for VGA, DRAM, and CPU respectively; My red CPU light is consistently on. It turns on immediately after powering on. I understand that this is the motherboard telling me, and I quote from the manual, "... CPU is not detected or fail." To further complicate the issue, my motherboard didn't come with a Mobo Speaker so I can't even listen to beeps to give me further clues as to the underlying issue(s). I have followed the "Not POSTing" troubleshoot thread to the letter, save for Breadboarding my system (which is actually a new concept to me), which I will do later today when I get home from work. And aside from this, I do mean everything. Again, I am very careful, meticulous even, about assembling my computers, I have checked my wiring extensively leaving no stone unturned... the CPU and socket both appear *perfect*... I have looked extensively into similar cases on Tomshardware and beyond, but none of the solutions I found have worked for me, and plenty more appear to have gone unresolved. I am saddened to say that for the first time in building a computer, I feel completely and utterly stumped... and so I turn to you peeps in the Tomshardware Thinktank for advice.

I'm thinking about just RMAing the Motherboard and CPU, because at this point I have no idea how to discern whether the CPU or the Motherboard is at fault. I imagine this is fairly easy to do through Amazon (I bought all my parts through them).? What should I do guys?? What could possibly be wrong .-. ? A million thanks in advance for your help and advice.
