Portal 2 crash after startup

[Killerbunny123]

I double click Portal 2 in my library, then it launches the game and I have a black screen for about 2 seconds, then the game crashes.

I already reinstalled, verified the local game files, and updated my drivers. I also deleted "videodefaults" under C:\Program Files (x86)\Steam\SteamApps\common\Portal 2\update\cfg with no luck

The specs on my computer are:

quad core i7-4700MQ 2.40GHz
16 GB RAM
Nvidia GT 755M Sli (x2)

Also, I bought the game during the steam summer sale and still haven't been able to play it :<
