Depois dao a resolução do erro, mas não percebo patavina, como sou ainda um pc novato em questão de manejo de Pc's, gostava que alguém tivesse a boa vontade de me puder ajudar..
Paged Pool Memory Issues
These crashes are most commonly a result of running out of a special type of memory called paged pool memory. Paged pool memory is allocated by the OS kernel for use in things like Direct3D resources. Running out of paged pool memory can result in Direct3D crashes (a.k.a. game crashes) and in Steam.exe using 100% of the processor. In some cases you may get an error message stating there there is an issue with paged pool memory. In most cases, you will not get any such error message - your game will simply crash.
Determining whether the issue is a paged pool memory issue
Download and extract Process Explorer.
Run Process Explorer. Press CTRL + i to bring up the System Information window.
Run the game in a window.
Go to Steam's My games menu.
Right-click on the problematic game.
Select Properties > General > Set launch options.
Add -sw to the launch options.
Launch the game.
Watch the System Information > Kernel Memory (K) > Paged Physical value. If the value exceeds 150MB, you are using too much paged pool memory.
Resolving paged pool memory issues
If you have determined that you are currently using too much paged pool memory, you can resolve the issue by closing processes using paged pool memory until the issue is resolved. You may determine which processes are using paged pool memory by watching the Paged Physical value as you close a process. Make note of those that result in the Paged Physical value dropping. Anti-virus and security applications are known to use large amounts of paged pool memory.
Acho que o que diz aí, é que esse problema que me dá, é devido a mts programas que tenho na barra do canto inferior direito, Emule, anti-virus, Msn, etc.. tenho que fecha-los.. mas sobretudo falam do AVG..
'Note:
In practice, we have found that certain antivirus systems allocate a large amount of paged pool memory that cannot be freed until the antivirus software is fully uninstalled. Specifically, AVG, Norton and NOD32 have been identified as antivirus packages that allocate large amounts of paged pool memory and directly interfere with Source engine games.'
Será que se o desinstalar o problema fica resolvido?? Tenho outro anti-virus instalado que é o Avast.. Desculpem por ter posto isto tudo aqui, mas é que é mesmo frustante não poder jogar este jogo depois de tanto tempo de espera

, quem puder dar uma ajudita agradecia imenso, mas acho que deve ser isso, antes de eu fazer algo, preferia que alguém tb explicasse se eu estou certo com o que penso.. Obrigado e desculpem..
