Windows 8.1 install - Most computer games not registering graphics card (Intel 4600 and NVIDIA GTX 645)

I am not sure what is the issue, but I am getting a lot of errors like this:

Or sometimes the games just look like this:

I am using Intel(R) HD Graphics 4600 and also NVIDIA GeForce GTX 645.

I never had any problems until I just updated to windows 8.1. I have checked the drivers and they are all up to date according to device manager and also iObits new device checker.

I heard there was a good 8.1 Nvidia driver update, but when I try to run it I get this:

    Its likely that your windows 8.1 update rendered your video drivers invalid. Please go to http://www.nvidia.com/Download/index.aspx?lang=en-us, download and install your latest video drivers for Windows 8.1.

    Also, if you let windows update run it may download the latest WHQL drivers on its own.

    Intel Corporation and Nvidia
  4. If you downloaded the drivers from the link I posted and they didn't work, please post screenshot of your device manager. If there are any devices with an exclamation mark, please post the error descriptions too.
