Starting UE4 crashes System

For some reason I had to repair my binery build of the engine in the launcher. Ever since I’ve done this, neither the binary nor the source build will start. Both crash the entire PC.

Trying to get Kinect to work today I had installed a Java Based APP called XEDConverterApp along with the standard java download, which was however a 32bit version. The app warned me about this so i also installed the 64bit version. The official java site stated having both versions installed is good when using different browsers requireing different Java versions s I don’t think having two versions of Java installed should cause crashing epecially since it doesn’t have anything to do with Unreal.

I got an error message stating the app couldn’t find the name for Intel CDI for OpenGL. Followng this link (https://communities.intel.com/thread/110921) I tried installing a driver for…something. The installer told me it couldn’t install. I then updated my NVIDEA driver over GeFroce Experience and now I can’t use Unreal Engine anymore. Starting the engine alone, not a specific project, let’s the engine load to around 73% when the screens will go black and the system reboots.

I since deinstalled the converter and the Java verisons, nothing changed.

Current NVIDEA driver is 384.76.

What could cause this and what could be a fix for this? I really need help
