I hope someone can help me with this issue. I have a Mac pro 2009 4,1 that was flashed to 5,1 before i bought it. It has had some issues with kernel panics, sudden crashes, etc, never any indication of what the cause may be.
Usually it freezes and then i just do a hard reboot and comes back up, but yesterday, it froze, did a hard reboot and since then it just won't boot.
The front power button led illuminates, fans turn on but nothing happens.
I got the service manual pdf and looked up the diagnostic led chart and this is what I get:
When the power cable is unplugged and I plug it back in, I get the two CPU diag leds to flash red for less than a second, and then if I press the DIAG button i get what you can see in the attached video.
I have removed the CPU tray (no red lights on any of the ram modules, CPU leds flash red when powering up but do not stay lit) and re-seated all ram modules, I removed the video card and swapped it for another one that I know works on another Mac Pro I have and that is as far as I can make it.
Any ideas, recommendations, etc would be more than welcome, I really don't want to buy another one with the supposed new ones maybe coming up next year but if i can't figure it out I may have to.
Thanks!
PS: I just swapped the 3v battery and the flashing green DIAG led is now not flashing anymore and stays lit. Still no boot.
