Boot failure after installing graphics driver

[TheSniperFox]

Hello,

 

something just caused a major boot / graphics problem to my PC. 

I was just browsing through the web and I got a grey / black screen. Fine, I just hit the reset button for reboot, but when Windows wants to boot up, I get a graphic failure and nothing works anymore. So I started Windows in Safe Mode, removed my latest Nvidia graphics driver and it boots just fine. So I installed an older version (from 23.05.2016) which worked just fine. Same boot failure again. Then I tried it with and old driver from last september, when I have built my rig. Same for this one. I cant even get the Intel VGA driver installed. So I am sitting here in without any graphics driver. 

I am running Windows 7 64-bit on a Asus Z170-A, I-7 6700K, Samsung 850 EVO, Kingston Hyper X 2133 16GB and KFA2 (Galax) 980 TI. Everything watercooled.

So changing components sucks even more. 

 

Do you have any ideas? Maybe reinstalling Windows will be the best solution, but actually I do not have interest and time for that. 

 

Thanks for all your help in advance.
