Hi Guys - I need the thoughts and advice from your seasoned Mac people - I have 2 MBP's - 1 15" aluminum, one last years model 17" Unibody (with Black around screen). The 15 has run great since day one. The 17" was ok, but now is locking up and causing me to reboot, fans seem to run on high all the time, and it is very slow to react while using the OS, it gets worse until it locks up. I have upgrade to Snow Leopard thinking that that might fix it, but it has not. When I got it, I restored from the back up of my 15" using carbon copy cloner. I only imported users and data such as pictures and music. Do you guys think that this is a hardware issue or a or should I back all my stuff up and then blow everything away and reinstall from the ground up with a fresh SL install? When I called apple they tried to sell me apple care and told me that it was out of the full warranty and if I send it I would to pay for what was not under warranty. SO I am hoping that someone has seen this and has a fix that I can do without having to take it in. Any help or guidance is appreciated.
