I pre ordered Fallout New Vegas back in June on Steam and ever since it came out killing in vats and sometimes out of vats makes me computer freeze, flash a blue screen that says something about some error and restart. I'm not sure if its something wrong with my computer or with the game as every other game works fine and I know FONV has a few bugs. Here are my computer's specs in case it helps.

Video card: NVIDIA GeForce 9800 GT

Processor: AMD Athlon™ 64 X2 Dual core processor 6000+ 3.10ghz

Sound Card: Turtle Beach Riviera

and 3.25GB of RAM

I built the computer myself nearly 2 years ago, all my drivers and DirectX are up to date and my computer shows no signs of viruses or anything else. I also have the caravan pack from the pre order. Not sure if that's relevant or not but there it is. Any help would be appreciated. Thanks.

Also whenever I validate the files through steam 1 file always fails to validate and even though it says its fixed it is hasn't. I've validated the files several times and every time it always says 1 doesn't validate. I've tried un-installing and re-installing and I'll try that again in the morning. Hopefully someone will help by then.
