Garry's Mod Not Loading Past Splash Screen


I am having a bit of trouble with my Garry’s Mod, this has only started happening recently.

With this thread I am hoping to not only fixing my problem but help others find the answer.

The Story:

So, I was playing gMod and decided to go to bed because it was late, the next day I woke up went on my comp and attempted to play gMod when all of a sudden it wouldn’t load and it was stuck this screen:

I have tried un installing and reinstalling gMod as well as steam. I also uninstalled the Sims because after I installed that it stopped working.

I have tried verifying my game cache still no luck:

I have tried to reinstall all of my source engine games ((CS:GO; TF2; HL2 etc.)I am having the same problem with these).

I also have tried to look through the depths of the internet and I can still not find a answer.

Thank you lovely people for helping.

Could you add me on Steam? I’d have just PM’d you some instructions but you seem to have private messages disabled.
