I have a 15 inch Macbook Pro A1150. I read some sites online, maybe you guys had experience and know better. Here is what I read: -I read that it may have to do with the RAM. (I got mine replaced, only 1 though, a couple months back because it was causing my screen dead pixels to spread. Once i replaced it, the dead pixels stopped spreading.) -Third party extension is causing it? Not sure what that means... -Hard drive was replaced a couple months ago too so i know its not that. I tend to use programs like Photoshop, Illustrator, Maya, and Microsoft Word. Sometimes I will have 2 or 3 open at the same time along with the internet. Maybe RAM overload? It is 2 GB. Maybe I need a software update? Its up to date right now. I did notice that when the fans get loud, the kernel panic comes on soon after. I keep my computer on solid surfaces like my desk all the time. I think it may have to do with the third party extension. I have way too many things that connect to the internet like Dropbox, or UTorrent (which i never remember giving permission). The reason I say is because when I log in the the guest account. I never get the kernel panic. ANY HELP PLEASE?
