As seen in the picture above, my Mac Pro is getting the white screen of death. Immediately after turning on, it goes to this - no startup chime, no Apple logo, nothing. I have tried: - Resetting SMC - Resetting PRAM - Holding shift on startup - Trying to boot into recovery mode (Cmd+R) But none of these change anything, the white screen stays.

  • Can you give us more information? Which model Mac Pro? What OS?

Rule 1 of troubleshooting, "Isolate and identify."

Remove anything you can to still have a bootable computer. That includes RAM, PCI cards, drives, memory risers. Then swap out the memory with the RAM you removed. Unplug everything, even your keyboard and mouse, leave only the monitor connected. And if you have another monitor you can use temporarily...

  • Hey Steve, thanks, this worked. I had a backup drive connected and it had failed in some way. Thanks for your help!
