Thanks for the reply. I have done a lot of searching on this, it seems there are others with the early '09 mac that have the same shutdown symptoms. Although i have not found anyone that had it shut off specifically from browsing, only when the computer was under heavy load. I can run Photo Shop for an extended period of time with out issue. Right after i posted 2 hours ago, my computer shut off. I have been browsing ever since. I did an ETreCheck I'm sure theres nothing out of the ordinary since this is a clean install of Yosemite. but ill post it anyways. Im just hoping someone else had a similar issue and resolved it. I like the new features of Yosemite and would prefer it over Mavericks...
