Alright this is getting on my nerves.
I previously had an issue with The Orange Box because I use AVG 7.5 and apparently it fucks with your paged pool memory usage and causes the games to crash.
So I uninstalled AVG to play Portal, but it still crashes and tells me I'm likely out of OS paged pool memory. It gets to the loading screen for the main menu and crashes.
anyone have this problem? Or had it and fixed it? :\
