No 3D game works anymore after messing with registry (GTX 560)

[Vicaris]

I followed the instructions on this video:
https://www.youtube.com/watch?v=DHoj8bQDjUc

I went to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers, then I created a new DWORD (32-bit) value named TdrDelay with an hexadecimal value set to 8.

I did that because windows was crashing Alien Isolation with the message "Application has been blocked from accessing graphics hardware".

As the solution from the video did not work, I went back and deleted TdrDelay. Now every 3D game crashes. The problem got worse after using D.D.U. and reinstalling the drivers for my GPU. Before, at least I could make the games run a bit before crashing and Alien Isolation actually seemed to work. Now nothing works.

Did you back up the registry before doing it?

Also try searching TdrDelay in regedit, it might have replicate somewhere else

I have not. I also realized that now windows 10 is blocking every application, so that's the new problem. I gotta fix this application blocking thing now. I figure once I do that I can fix everything.

Apparently the default value for that is 2. So since you deleted it entirely maybe that's the issue. Try adding it back again and this time give it the default value of 2.

Tried that but not sure I did it correctly. Found nothing. I clicked "Edit", "Find" typed in the name. Nothing came up. The selected folder was the GraphicsDriver one where I created and deleted the file in the first place.

I tried that, didn't work. Then I tried just recreating it with a value set to 8. Seems to have fixed it. Alien Isolation is still crashing though. But this time I'm not getting the application blocked message. Temperatures reached 85°C when it crashed. Might've been the cause, not sure. Gotta test some more games again.
