Yeah so my PC is basicly a clean INstall of windows vista with all the updates right and before I did the clean install all my steam games would work like Portal, HL2, HL2 epi1 and 2, TF2 and ect. But recently I decided to go head and reinstall those games so I did and guess what, none of them work. Basicly whenever I double click to open one of those games, I get teh preparing to launch "the game" and then an error message hl2.exe has stoped working. I have no idea how to fix this anyone know and care to tell me.
