So I upgraded my motherboard, cpu, and ram (M5, 6600k, hyperX 2x8GB @2400MHz).

I am reusing my M.2 (OS & fav titles), 2 SSDs (mostly install directories), and my 2TB seagate (mass storage, media, etc.). Power supply is corsair RM1000. H100i V2 cooler. That's all folks.

It all started with my first set of these 3 parts (mobo, ram, cpu) when I plugged my fury x in and connected my MG279Q to the fury with DisplayPort. Once I pressed power button, here's what happened : https://www.youtube.com/watch?v=EAwgnQQ1A8Q

Power just went on off on off on off on off.....forever.....

The symptoms kinda stayed after that point. I removed the displayport as the monitor become unresponsive. I tried HDMI in the fury x, the startup was different in that in only when ON, OFF, ON....then stayed on, like a double start....the monitor was still unresponsive but the PC wasn't doing the on/off/on/off/on/off/on eternally.

I removed the fury x entirely and tried the onboard HDMI....same story... ON, OFF, ON...monitor unresponsive. I RMA'd the monitor. And the Fury X.

I switched over to my old 1080p monitor. I also reset all the pins/connections all over the motherboard and hard drives. PC still went ON, OFF, ON. Sometimes I could get to windows, sometimes not. I disconnected all my hard drives. Essentially no difference, still random, still doing the "double start" when i press power button.

I tried reconnecting drives. Sometimes, instead of booting to windows, it would just not display anything on the monitor and the motherboard code reader would show "00" and it would just stay here until i killed the power.

After resetting BIOS, clearing CMOS, updating bios, trying all combinations of drives, sata, power, etc. I went back to microcenter and swapped the CPU, motherboard, and RAM again.

Tried it all again.

Installed ONLY the M.2 now (which had the appropriate MSI drivers on and such for that identical motherboard.) First thing it did, was a doublestart... ON, OFF, ON with one press of the power button. It performed it's typical first-start testing and such, restarted once or twice, then booted to windows. At first everything seemed ok. I tried shutting down and cold starting. Sometimes it would simply go ON with one press of the button, sometimes it would do the doublestart (ON, OFF, ON) with one press of the button. Random.

I tried connected drives. First one I connected, the motherboard went ON, OFF, ON and displayed "00" on the code reader and monitor unresponsive (it never boots anything when 00 is displayed). So i was like, aha! something is wrong with this drive! but i plugged all my drives into my Surface Pro 3 via USB and confirmed they all worked. I killed the power, waited a few minutes, tried again. ON, OFF, ON but now it suddenly boots to windows and i can see the drive in my explorer. Tried the other drive, more complications, "00" boots, ON/OFF/ON, etc. Sometimes it would do the doublestart (ON/OFF/ON) but still get to windows with both drives, sometimes "00" and nothing.

This has been an absolute sh*tshow and I am very, very, very exhausted. I build a PC every 1-2 yrs and have never had anything go this sideways. Usually I plug everything in, and it works. I even reinstalled Windows on my M.2 and lost everything, including my CD key which wasnt linked to my microsoft account. now i get to go spend $120 for another key. lucky me. As i said i'm tired and i do believe i have tried everything. please help. I am willing to skype via my surface pro 3 if any pros are willing to dictate commands for me to attempt in troubleshooting. MSI why have you forsaken me.
 
If you haven't tried breadboarding your set up, start there. Motherboard, CPU, one stick of RAM. I would have guessed your issue was swapping the motherboard without doing a fresh install of Windows. This rarely works without issue, but since you have tried reinstalling Windows, you need to look elsewhere. I would say your RAM is the likely suspect at this point. If you can get it to boot with one stick, select the XMP profile and reboot. If it's good, try installing the other stick and booting again.

It isn't the ram. Apparently with the stupid lga 1151 pins being on the motherboard, there now exists a potential for people to over tighten water blocks. Which I believe I did. Because I loosened the corsair h100i v2 block, almost to the point where I felt it was going to fall off, and the problem went away, sort of.....

Now it sometimes boots, simply going ON with one press of the power button. Sometimes it'll do ON/OFF/ON with "00" error code and will stay there forever. And sometimes it will go ON/OFF and stay off forever, failing to boot.

I'm still more or less lost. Really doubt the ram has any involvement.

It just happened again. (i'm posting from my surface btw). It went ON/OFF/ON and stayed at "00". i killed the power and adjusted the screws on the water block. Literally feels like they aren't pressing the copper against the top of the CPU at all.....but sure enough, i pressed power button and it simply went ON. Now I'm in windows.

So, proving my "feel" of the screw tightness, my temps are idling (at desktop) at 48, 50, 44, 43 *C under 0.8% load.....this doesnt make any sense.....

If i tighten the block, my temps will go down, but the PC won't boot. this is insane.
