    Hi everyone! I am currently experiening a problem with my Mac Pro 2,1.

    I purchased this used last December, from a professional video editor/colorist, it was in excellent working condition with a powerful processor and VG card.

    Here are the specs:

    Apple Mac 2,1 Pro 8-CORE

    -3.0Ghz (2x Quad-Core)

    -32GB RAM |

    - GTX-680 4GB V-RAM

    - El Capitan (SSD)& Yosemite (HD) OS on dual drives

    As of recently, it began to suddenly shutdown (two days ago) when I would work on my photographs via RAW camera filter, using Photoshop CC; a GPU error would show up right prior to shutting down. I also noticed that the machine would feel quite warm to the touch. (at the bottom rear)

    I let the machine cool down (about 1 hour), opened the side compartment, and used canned air to blow out the build up of dust, hoping that was the problem. Afterwards, I tested it by doing light tasks and it suddenly shut down again after about 35 minutes; which has been the window of time I can operate the machine. When I would restart the MAC, it would shut down shortly after the password log in screen would appear.

    Has anyone been experiencing or experienced a similar problem? I would have no problem finding a remedy for this issue. I thank you all in advance for any sort of pointers/assistance/help.

    Best,

    Matt

    It's possible you are experiencing thermal shutdown and 35 minutes is the time it takes for the computer to heat up to that point.

    Are any of the fans going crazy speed? Are any of them dead (not spinning at all)?

    I suggest installing fan/temperature monitor to confirm whether or not that is the problem.

    Actionable Mango, thank you for your reply. When I powered the unit on, It appears that the fans are running smooth and quiet as usual.

    I am going to try out the application you suggested, as I am still troubleshooting. Thank you! :)
