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!

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

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.
