I'm sorry to be one of those people, but I'm desperate here. So, my 3 year old MacBook, before I did a full wipe and reinstall of 10.6, was having problems playing even simple youtube videos. I figured out that the processor was getting to hot for some reason and just wouldn't cool down playing Flash 10.1. I then tried to make a dual boot Ubuntu 10.04 to see if a different OS had the same problem. Well, I ended up screwing it up and my MacBook out of 10 gigs and I just said enough and did a fresh reinstall. Things have been great up until today. My MacBook just too 10 minutes to go from clicking my user icon to entering the password. This morning it was very slow, and I shut down and restarted quite a few times with no result. I tried a hardware diagnosis but it wouldn't boot into the CD at startup. Please help.
