I'm having a problem with HL2 Episode 2 on my PC - surprise, surprise. I love Half-Life 2, but I'm getting sick and tired of these issues.

Ep2 actually runs flawlessly at 1680x1050 on my PC. However, I have to start the game from a fresh reboot every single time or else I get a error with internal driver error which supposedly is a pagefile size error. I've already increased my pagefile to 3070 minimum and the 4000 maximum size. If I play the game, quit it, and then try to restart it... I always get the error. Once I reboot, I can start it up no problem. I 'think' it happened when I tried to start portal as well if I recall correctly. Steam says some programs use alot of pagefile and list AVG anti-virus as a culprit - which I use. But I am not going to uninstall my AVG for a source game when I have this problem with no other games at all.

Any suggestions?
