intox Gaming

I was playing CSS today and I quit the game to go upload a few skins and then I tried to go play Bigloop and it closed my game and this error came up. I have had it before and I think I have to update my drivers or something (I know shit all about comps.). Can someone help me out?

I have no clue how to update mah drivers.

That's happened to me a few times. Did you restart the computer when that error happened? It's starts working again when I restart the computer.

No and I have had this before and it hasnt worked in the past
