Rainbows of Un-Happiness

So I got a new laptop in late June. I immediately installed Steam, Gmod, Etc.
It worked fine for the first month or two, then, with no evident cause, most maps created rainbow triangles that came from the skybox among other technical bugs.
Such as: The Q menu becoming invisible, skyboxes hating me, inability to use any post processing things, bugged flashlight.

Has anyone have the slightest idea as to what this is?

Now, keep in mind, I’ve had this problem for a few months now, but I finally decided to make a thread.

Also, Gmod refuses to start up. It just shows the loading bar and it never goes beyond “Creating Render Targets”

I suppose I should also add that Episode 1, and most other games work fine. (High settings, etc.)

Rate OP optimistic.

Also, it may be because your graphics card is shitty.

Yeah, I typed anything that looked relatively important.

You have a terrible laptop onboard gpu, it’s probably overheating or something of the likes.

Terrible you say?

FYI EMBseries
:bandwagon:

It’s still pretty terrible for playing most modern games, or are you forgetting that San Andreas is about 3 years older than Orange Box Source engine? Everything in the OB engine was upgraded from HL2’s engine, and I can see that he’s running ENB Series but that doesn’t prove anything really.
