Ok, my ISP sucks so, long story short, I had to do a reinstall of Snow Leopard on my 2.0 CD MacBook. I did this a few days ago, everything's up to date and set, and since then, it's started freezing in the middle of something. Other times I may have had a processor intensive website or something in the background, but this last time all I had was a video playing in iTunes. It could be that it's overheating, but shouldn't it warn me or something instead of just freeze? Will it unfreeze once it cools down, if this is even the cause? All times it has frozen my new iPhone 4S was plugged in. Also, I did the reinstall right when the latest version of Safari came out, and Safari has been open each time it froze. Thoughts? Suggestions on how to pinpoint what's going on?
