It just ran out of warranty in December too! Fuckin thing sucks! It started off with me waking up this morning, my computer was locked up. I went to restart it and it booted up slowly. Random files were missing and I kept restarting and sometimes it would hang. I picked up a new hard drive and replaced it, the computer wouldn't ever load Leopard and I tried two disks and tiger. Finally. I opened it up and checked the connections and put it back together and now it won't even turn on. I know it's not the power supply because the first LED of 4 on the LogicBoard stays solid when it's connected to power. I've tried everything I can think of. 1. Reset PRAM 2. Tried new ram 3. Took Out CMOS battery 4. checked connections again 5. Tried booting it up with just a basic keyboard and mouse (nothing else attached) It won't boot up at all anymore. Suggestions? EDIT: So this morning I plug the computer up and hit the power button, it takes nearly a minute but finally it chimes and goes to a flashing folder with a question mark (after about another miniute). I put my leopard disk in and reboot, Everything seems to be going fine until all of a sudden the time of installation stretches out to over 8 hours and then the computer just reboots!
