Installed new components, GMOD closes on startup.

[Frezno]

I had a problem before where GMOD wouldn't start as it would just close on startup (the blue screen with loading in the corner). I had fixed it by reinstalling the game but now it seems the problem is back and doing what I did before isn't working.

What I did
1. Reinstalled GMOD
2. Verified GMOD in Steam
3. Ran with a variety of launch parameters
4. Fully installed a huge amount of DirectX and DotNet packages
5. Installed 15 different Nvidia drivers (to see if Drivers were the problem.)
6. Revert OC changes

Now I know this is related to GMOD13 specifically because GMOD12 and 9 run flawlessly, so I'm very confused at the moment.
I'd really appreciate the explanation on the stars (***) part but not sure what ntdll.dll has to do with anything or symbols.. yeah.

Edit: Oh and to avoid confusion, GMOD13 was working perfectly with my old specs before I upgraded my PC.

How do u have gmod 12 and 9? Isn't the only way to get them is to pirate?

[Frezno]

GMOD 9 was a very good gmod and so was GMOD12, I opted to keep them by disabling updates to GMOD and re-dowownloading new versions.
There is an easy workaround to do which is disabling updates to GMOD, rename GMOD folder like the picture below, goto steam and redownload GMOD.

Now when you want to play GMOD9 or 12 all you have to do is switch out the folders names and launch. I heard there is other ways of doing this like adding the changed folder name to steam shortcut + parameters in launch options, in theory could work since Steam still thinks GMOD is GMOD.
Anyways besides that, anymore questions?
