So I have a late 2006 MBP 15" 2.16Mhz 3GB RAM. I have tried all the usual things like resetting PRAM, etc. I've reinstalled SL. I've downgraded to Leo. No apps installed, no plugins, etc. Still when I boot it, it reaches the blue screen and stays there for about 10 minutes or so. It's been doing this for months now. I installed a new HDD yesterday, no change. I ran MEM TEST on it, all OK. I cleaned out the fans and heat sink, put the thing back together... it works fine once it's booted, but it takes forever. I make sure WiFi is off, so it doesn't look for an ext HDD. Also, sometimes I'll put it to sleep... it will... it'll go black, etc.... but then later I notice it's getting hot even though it's asleep. ?? EDIT: I think the OS is fully booted, but it just won't show itself... for instance, if I tap a bunch of keys while still blue, when it finally does go to my desktop, there might be an app launched because I was tapping keys... Just now, it was stuck on blue - so I used the remote to see if that would do anything... nothing at first, but when it finally "woke up" Front Row was launched - so I know the OS is up and recieving commands. What could keep the screen blue while the OS is booted? Any ideas? I want to fix this before I sell it. I recently bought the 2011 13" MBP.
