Hey I just got steam installed on boot camp (vista 64) and wanted to test some games. First I installed new drivers, 178.08, and they seemed fine, it didnt even give me an error when I installed like nvidia drivers usually do. So I opened TF2 and it ran really well with the settings maxed and 2 AA. Then after about 10 mins it froze with the sound looping. What do you think is the problem?
