Background Applications

Graphically intense games such as Half-Life 2: Episode Two and Team Fortress 2 require a large amount of your system's resources to run. Having background applications running while you play can often result in the game engine competing for system resources with other applications. Often times this can result in the game crashing because there is not enough system resources free for the game to utilize.
It is also important to make sure that your system has enough paged pool memory available.

Anti-Virus Software

Certain anti-virus and anti-spyware software such as Norton/Symantec, AVG 7.5, Avast, Spyware Doctor and Nod32 have been confirmed to cause game crashes with Source engine games. If disabling your anti-virus and/or security software does not help, you may want to consider completely uninstalling these applications until an update is released by the anti-virus software developers that resolves these compatibility issues. More information can be found in the Troubleshooting Game Crashes FAQ topic that is linked above.
