HELP! After installing Corsair H100i v2 my GPU stopped displaying and doesn't show up in Device Manager.

My parts:
MSI Z97 Gaming 5 Motherboard
i7-4790K CPU
MSI GTX 970 GPU
16GB 2400mhz RAM
EVGA NEX650G PSU

Problem:
Bought H100i v2 today. Installed it carefully, fit in, everything is great. Put my PC back, connect the cables, turn on and my monitors aren't showing. Solution?

Things I've tried:

Refitting GPU x5
Refitting RAM x5
Taking out CMOS x3
Refitting CPU x1
Refitting pump/cooler x1
Reinstalling Windows x1


I'M REALLY DESPERATE FOR THE HELP. CAN'T FIND A SOLUTION AND CAN'T GET MY HEAD AROUND AS TO WHY MY GPU JUST DECIDED TO DISAPPEAR!

  1. Have you made sure that the power cable(s) was reconnected to the video card?

    Yes, I'm 100% sure power cables are working since GPU is lighting up and spinning as normal in the case.

  3. Hello! i've had a similar problem but mine was booting up ocasionally but would crash after a few mins. If your gpu has two separate psu inputs try connecting it with 2 separate cables, maybe that will help.
    And if the mobo has a VGA led is it on? if so the gpu is not recognized and you have to do some troubleshooting more.
