Portal 2 Crashing During Gameplay With No Error
I bought Portal 2 during the Autumn Sale last week. I've been playing since Monday, but only at about 10-20 minutes at a time before it crashes to desktop without warning or error message. I've searched through these forums and it seems like people are having this problem and similar problems, but none of the solutions are working for me.
None of my other Steam games exhibit this behavior. Every time this happens I verify local game files, it says to has to reacquire one or two files, it "finishes the installation process," and then I am able to play for another 10-20 minutes before it happens all over again.
The only "Tools" I have installed are SDK Bases 2006 and 2007, and I also verified those to no avail.
Luckily I am able to reach a few checkpoints before a crash so I can actually advance through the game, but this is getting ridiculous. I've logged about 3 hours of total playtime and have over a dozen crashes.
My computer is only 4 months old so I don't really think that is the problem, but since I know people will ask, here are my system specs:
Intel Core i5 3750k
NVIDIA GeForce GTX 670
16 GB of RAM
Gigabyte Z77X-UD5H Motherboard
Any help would be appreicated.
