Windows wont start after installing graphics drivers

[w0rmh0lez]

Hello guys

So today I finished my system which consists of a Rampage IV Formula motherboard with a 3970x cpu and two HD 7970s with the cross fire bridge on. My power supply is a Silverstone 1200w Gold rated.

I installed Windows 7 64 bit and updated and installed a few other drivers and rebooted and everything was fine. Then it came to installing the drivers for the video card so I went to AMD website and downloaded the latest ones. It installed and then prompted for reboot so I did.

However now It won't boot into windows. I just get the Windows loading screen and the the screen goes black.

I've tried reinstalling Windows but that did not help either and same thing happened. Please help!

how about try with just one gpu first?

@rgd1101 I cannot as I have the system watercooled so it is not possible for me to remove one card without completely taking everything apart.

Firstly check the bios if the primary graphics card is not on board but the PCI express itself , if its there pull out the graphics card plug the monitor wire into mobo and boot the computer , now go to control panel and then check the display drivers ,
If the mobo has inbuilt gpu it would be enabled , right click on it and disable that ,
Sometimes motherboard takes the primary card as onboard one even after the settings are applied in bios itself
And please update this forum after that
