Mac Pro 4,1 Won’t Chime or Display
I recently purchased a Mac Pro 4,1 off of Facebook Marketplace listed as “untested”. I get it home, plug it in, and get a CPU error light on the board (single cpu board). I wanted to upgrade it to a dual anyway so I just bought a dual board that included CPUs and swapped over the RAM after repasting the CPUs. After this, I plugged everything in and now the fans turn on but I don’t hear a chime and I don’t get any video output. What should I do?
The specs are:
2x4GB Crucial ECC DDR3 memory sticks (one in each bank)
2x Xeon E5520 processors
Nvidia GT120 GPU
No storage installed currently
What I’ve tried:
Reseating just about everything
Resetting PRAM and SMC
Moving the GPU to a different slot
Swapping around memory sticks/using different sticks
Adjusting tightness of CPU heatsinks
Removing any extra PCIE cards
Replacing PRAM battery
I’m wondering if maybe it’s because I’m using a mini DisplayPort to HDMI adapter to connect it to a monitor but either way I’m not getting a chime so I doubt it.
I’ve included a picture of the Mac Pro and a picture of the diagnostic LEDs when it’s powered on.
