Welp.. its saying engine error on the top and since GMod and CSGO are both based around the Source engine its no wonder that those 2 games are affected.
Although.. have you tried running other Source games like HL2, CS:S etc.?

Is your Windows Version up to date?

Which graphicscard are you even using?
If it is one from Nvidia (which I hope it is) try updating via Geforce Experience and not via Devicemanager.
You should also check if you've got DirectX 9 installed.

And if all of this fails: try turning it off and on again.
