Steam games not working

[Bad Dog]

Well my other computer got bum fucked by viruses, so I am on the rarely used "family computer" So I downloaded steam and can access my account fine, I redownloaded CSS with no issue and bought GMOD, but noticed somthing wrong. I cant launch GMOD or CSS for some reason. I click the icon and the little start up pop up comes up like normal, disappears like it always did before the game window opens up but nothing happens the game doesnt launch or anything. Help please?

Make sure your Hl2.exe isn't running when you try and start a game. Same thing happened to me. Just go to task manager and end the hl2.exe process.

Mine does this too. Did you restart the computer? This usually fixes mine.

I had to change the DirectX level on my laptop because it used to load and then crash right away and made me mad. Try adjusting your -dxlevel in your launch properties.
