Help me!

I installed Hl2 on steam now that works fine, but I also installed HL2 Dm and CSS and what do i get with vista. O hl2.exe has stopped responding upon startup. please help if someone know what the heck this is.

update ur drivers

i usally get that when im running a bunch of shit and minimize constantly

all my drivers are up to date and im running nothing in the background while trying to run it.

Try a reinstall, may be a corrupt file somewhere which doesn't agree with the rest of system, do it just in case.

I reinstalled steam and all games and the same thing happens

Reinstalling rarely helps with that problem on Vista.
Hopefully we can forget about it when windows 7 is released.
