Installed Corsair H100i v2 and my monitors won't show anything. Works only on onboard graphics.

Hello. Installed new cooling system today which works great, however after turning my PC on I noticed my monitors don't show anything, but my GPU and everything else works fine in the case. Fans spinning, temperatures cool etc. What could be an issue for my GPU to randomly stop working after installing cooling system?

Things I've tried so far;
Taking my GPU/RAM out, and putting them back in.
Resetting BIOS.
Taking battery out.
Turning PC on without having cooler hooked up to the power.

Nothing has worked as of yet. Any ideas on how to fix it? Don't think my card has fried, because it showed up in the device manager as hidden device before I uninstalled it as it was suggested, then restarted the PC and it doesn't show up anymore.
I really need to fix this. Thanks for the answers!

Can't find the option for my MSI Z97 Gaming 5. What if I turn off onboard graphics and my GPU still doesn't work?

I took my CMOS out already for about 20 seconds, then put it back in alongside with resetting RAM/GPU. No luck. How could my GPU just randomly decide to give up after simply installing the cooler?

Remove the cooler and reseat the processor. You will need to apply new thermal paste and do not tighten the cooler down as hard.
You could try to loosen the cooler just a bit first.
Their nonothing to do in BIOS when you install a video card it defaults to the card.

But if that's the case, why GPU specifically doesn't work while my onboard does?
Temperatures are 27 at idle as seen here - http://prntscr.com/gl940w

Took off the water block, took out the CPU, put it back in, re-applied thermal paste, put it back up, launched PC with cable in GPU. Nothing worked. Put the cable back in onboard and worked. Any more solutions?
