Well, I had an error (which I don't know what caused) and Windows wasn't booting anymore. So I had to reinstall Windows and lost a lot of programs, but saved my steam games.
For some reason I can play Team Fortress 2 (I think it's because it is on very low setting to run without lag), but Gmod doesn't work, probably because of a lack of some drivers that I haven't installed yet and DirectX.
It is a simple thing to fix, but there are a lot of other programs that I need to reinstall, and I'm on a week of tests in school, so I'm studying more, and this means no devianations for a while.
