I bought Crysis 2 a few days ago off Steam. Installed it, played it; everything was fine. Then, after the 1.2 patch as far as I can tell, I cant load past the intro logos. My computer just tanks for some reason, I cant alt-tab, Ctrl-alt-delete or anything. I have to manually reset my computer. I tried uninstalling it and downloading it again. Ran it afterwards and everything seemed OK. Played it for an hour or so and closed it. Tried to load it up again, bam, same problem. As far as I can tell my computer should be able to handle it just fine, and it worked for a couple of days. I seem to be the only person with this problem. Halp!
