Your description does not fit the classic NVIDIA GPU issue, however, it still may be caused by it. First, go to System Profiler > Hardware > Graphics/Displays and see if you have the GeForce 8600M GT GPU. This is the GPU covered under the free repair program. While there, also look at PCIe Lane Width. If it says anything other than x16, the GPU has issues (but this is only one potential symptom). If you have the 8600 GPU, bring the MBP to an Apple Store or AASP for free testing. If Apple's free test confirms the issue, repair is free. Read all about it here: http://support.apple.com/kb/TS2377
There have been stories of, ummm, "uninformed" workers, so print out the article, familiarize yourself with it, and if you meet resistance, politely/firmly stand your ground and ask for someone higher up the food chain if need be. The GPU is part of the logic board, so "repairing" it means replacing the logic board (Some workers have tried to play word games, saying the logic board needed to be replaced so it wasn't a covered repair because it wasn't just the GPU. Grrrrrr!). Good luck!

Thanks for posting this article! I do have the GeForce 8600M GT GPU (256MB) in my Macbook Pro. I went in to the System Profiler and found that it had the following details:
Chipset Model: GeForce 8600M GT
PCIe Lane Width: x1
VRAM (Total): 256 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0407
Revision ID: 0x00a1
ROM Revision: 3212
I noticed it shows x1 currently - does it matter that I am in Safe Mode?
I'll definitely be scheduling an appointment to be seen by an Apple Store for this issue. Thanks again for your help and I'll report back after going in for a test.

I've never looked/read about looking while in Safe Mode, so I cannot answer your question. The x1 is a classic symptom, so it sure gives me pause. Definitely off to the Apple Store with it. Good luck!

Thank you for posting this thread! I've been trying to boot up my MBP since yesterday and as soon as it came on and the apple showed, it froze. I was so... so... so.... scared that I would loose all my data since I run Pro Tools on it and have all the whistles and bells turned off. (no backup etc...)
But now thanks to your posting how to boot up in safe mode I have been able to boot up and backup all my stuff and undo the only change I did before this problem started.
I installed "Broadcaster" software from uStream and worked a little more on my computer with other stuff, then powered it down and went home. When I got home yesterday the unexpected began, and man was I scared!!! lol...
I removed that program that I installed yesterday and backed up my stuff and I'm ready to reboot. I'm keeping my fingers crossed, but at this point it doesn't matter if I have to reinstall the OS since I'm backed up. I even cancelled my appointment at the apple store! :-)
So thank you! thank you! thank you!
