Q: Intel based Mac Pro is not powering up even after SMC

I have an Intel based Mac Pro that is about 7 years old with 32GB of RAM. It is used exclusively in my recording studio. About 6 months ago it started not wanting to power-up. I would push the power button and my iLok flash drive would light up but not the light above the power button, and nothing was booting. I would hold down the power button until I knew the computer was completely off (SMC). I would then hit the power button again and things would power up and I would be off and running.

I moved the computer into a new space and hooked up some new peripherals via fire wire and HDMI. Now it does not want to power up at all. The little light on my iLok lights up, but the computer does not boot. So I read through some threads and unplugged the power cord and took off all of the fire wire devices so there is nothing left but the monitor (via HDMI) and my keyboard plugged in. I can get it to boot up at this point, but not consistently. When I plug in all of the other devices via fire wire and USB ( Glyph External drives, and a Focusrite Sapphire Pro 40- this is an audio interface for recording), Everything seems to work fine for about an hour, then I get a screen that comes down and says:" You need to restart your computer. Hold down the power button for several seconds or press the restart button". When I do this, I then get to start the whole process over again.

 

Does anyone have any thoughts? Hard drive? Motherboard? Power?  I appreciate your input. thanks!

    You need to restart your computer. Hold down the power button for several seconds or press the restart button".

    Kernel panic.

     

    Your Mac leaves a "suicide note" that note is stored in a log and can be read out from the location listed in this article. Use caution, there are several different similar folders nearby.

     

    Copy the latest kernel panic report (it must say kernel panic) to a reply on the forums. The text, not a screenshot, and not any other kind of report that does not say "kernel panic" near the beginning.
