[QUOTE="chscag, post: 1775352, member: 46727"] You're not putting anyone out here. :) We will try to help you out best we can. Most of us have come from the world of Windows and PCs and some of us run both systems. Macs are just not as easy to tear apart and get into as some Windows machines are. You probably already realize that Macs are very proprietary machines and Apple does not publish schematics or service manuals. According to the info you provided, your MacBook Pro shipped with macOS Snow Leopard 10.6.6 installed. Apple lists the machine as vintage and will not work on it or even look at it. OK, so much for that. I don't think the Snow Leopard DVD purchased from Apple contains 10.6.6. I believe it's only 10.6.3 which means it will not boot that machine. And trying to boot from a Snow Leopard USB flash drive is likewise not going to work. You may be able to boot with an original 10.6.3 DVD that came with the machine. I'm not sure Apple still has those in stock. You would have to give them a call and provide the SN of the machine to find out. Also, it's possible the DVD drive in that machine is not working right. Optical drives used by Apple in their machines are not very robust since they're designed to look nice and are slot drives not tray. Another thing about that machine you should know: The graphics used is a dual chipset: AMD Radeon 6490 or 6750M and an Intel HD 3000 (auto switching). The GPUs in those machines have been problematic over the years and many of them failed. Apple had a special repair program for awhile but it expired long ago. Based on the fact that you can boot the machine from USB is a good sign that the graphics are OK and the logic board is functioning. If the internal hard drive is not seen when you run Disk Utility from the external hard drive, it's possible the internal drive is not formatted. It has to be formatted as Mac OS Extended Journaled, GUID partition scheme. Hope some of the above helps. Let us know. [/QUOTE]
