2010 Mac Pro 5,1 2x 2.93ghz Westmere
20gb RAM
OWC 256gb SSD
ATI Radeon 5780
The last time this system booted (at all) was just before I took out the GPU to try in another Mac Pro.
Once I reinstalled the GPU:
- system starts up
- front power button light illuminates
- all fans run
- gpu fan runs
- brief flash of red light from CPU/ RAM tray (on start up)
what doesn't work:
- cannot reset NVRAM (no chime after many attempts)
- dvd tray will not open from keyboard button
- keyboard caps lock does not illuminate
- red light inside scroll ball (mouse) does not illuminate
I've tried to boot into Safe Mode, Verbose Mode, every mode..... I've tried resetting SMC, NVRAM (as noted above). I've left the unit unplugged overnight (14 hours), I've taken out all RAM, removed all drive(s),
Cold restart at least 20 times.
No chime, black screen - nothing.
PSU?
Thoughts?
