Computer crash at launch of steam game

[dragon12dk]

and the title says, my computer crashed at any steam game launch, Say Borderlands 2. my computer crashes as soon as I click Play on the popup, same goes for Saints row, and Red faction amageddon. the thing is though. I have tried downloading a cracked Saints row game. and it worked perfectly that way. can anyone help me with this?

Everything simply freezes but I can move the mouse and after like 20 secs it restarts

Have you tried reinstalling steam itself?

Have you tried reinstalling steam itself?

how do you do that? just delete whole steam itself?

1) Back up your Steamapps folder in the Steam directory;
2) Programs -> Uninstall -> Steam;
3) Download -> Reinstall -> login;
4) Copy steamapps backup back -> use Steam to Repair games.

This will tell you if it's Steam or something else.
