look for a computer with a fast processing speed, graphics card. Before beginning any work on your Mac Pro: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors. However, if your laptop computer will be your primary backup computer, and you'll need. When you're replacing your card, be sure to reapply a layer of thermal compound. Lets clear those up, and learn how to temporarily fix t. The procedure is shown on one card, but it is essentially identical for either.
I think we should all push for Apple to extend their board replacement program to include mid-2010 systems - the graphics problem seems to have been caused by Yosemite bloat. The 2008 MacBook Pro is a troublesome laptop, but many misconceptions exist about why the GPU breaks. (Alternatively, the OS after Yosemite is supposed to be more efficient, so it may make this problem go away i.e., it may be possible to upgrade immediately to Yosemite, then upgrade to the next OS.)
If that works, I'll just stick with Mavericks until the time comes to buy a new laptop. I plan to also wipe the hard disk, reinstall Mavericks, and not upgrade to Yosemite. One fix is to go into EnergySaver and disable automatic graphics switching (which consumes more battery power, unfortunately). I finally read somewhere that people were taking it into Apple, and that the March-June manufactured 2010 Macbook Pro 15 inch has an issue with the logic board. It seems that Yosemite requires more resources than the GPU can deliver, and the crash is triggered when the system tries autoswitching between the motherboard processor and the graphics processor. Running Windows 7 64bit under Bootcamp 3.2. Apple says motherboard failure (from Video Switching Test) and offered to sell me a refurbished motherboard for $310. System crashes and reboots, or screen just goes black. Apple now has a special Video Switching Test to identify this problem.
