Mac Pro 2008 P- Fan Speed Varying - No Boot or Video
My Mac Pro started acting weird, freezing up randomly but with long uptimes, then with increasingly shorter up times. Now won’t boot at all. Chime is also erratic. I pulled everything but the video card and keyboard. No video since it when down. At first the machine would start, no chime, optical would spin up, the main drive would spin-up, then stop, and then cycle again and repeat this cycle continuously. I checked all fans and they are working. However, on the last try I heard a fan that is weirdly changing speeds going from slow to fast, fast to slow.
Could I have a bad PSU?
I can’t believe this box is 11 years old. It has served me so well. I’ve got SSD PCIe cards, and an extra graphics card. I’d love to save this machine. She’s been so good to me.
