I was on vacation for the past month, and when I got back I updated everything on my Macbook (2.4ghz). I believe 10.6.4 was one of them, and Safari 5. Since the update I've gotten about 4 kernel panics in the past 7 days. Prior to this I haven't had any problems. These kernel panics seems to occur when I'm using more program. I'll have Safari, iPhoto, and Photoshop running. I've use this machine with these programs running at the same time prior to the updates and I've never had this problem. Safari also seems a bit odd sometimes, running slow with video and just now, I was browsing through amazon, and blocks of random graphics came up. They stayed there no matter what page, and even onto my desktop wallpaper. It went away after a quit. Could it be the updates? Safari? Hard drive crappin' out? What can I do to resolve this?
