Chosen Solution
My Mac Pro just switched off, and its not coming back on, its dead! After googling it people say it could be the logic board, but most likely the power unit its about 6 years old, i got a second hdd installed before, worked fine but then the mac would not start up (flashing question mark) seems to be a common enough issue but that was resolved, the hdd was not installed correctly. This time the mac is dead, at first there was no noise, no lights nothing, (it turned off while i was running final cut pro 7) Now after i disconnected all cables everything, reconnected everything and pressed power button for 5 seconds i looked back at machine and noticed led on monitor is on, and i can hear some very low noise at the back of the tower, where the power cable connected This was left idle for over a year but the last 6 weeks i have been using it solid most days, and i did notice it was a bit nosier than usual, kind of a humming noise but i did not think much of it? Its full of dust inside it, anyway this machine did turn off and on by itself for no reason a number of times since i started using it again, and sometimes did not turn back on by itself. So i am not sure if it is the powersupply or logic board, but if its the power supply I plan on buying a replacement , do i need a specific one for my model? And i dont know how to replace the power supply, so any advice or videos would be great. And if its the logic board… im completely lost there… I will try to give enough details for you about my machine, Mac Pro MacPro1,1 2.8 Ghz Xeon Intel Core 2 Duo 3gb Ram Model number - A1186 EMC Serial - YM63400RUQ2 If anyone can help me id be grateful, i will be attempting this myself as i can not afford anything else, eg apple repair store ect Thanks Shane Update can anyone help :) im not sure what to do
I had one of these up until this year (The 2.66ghz) and they can be extremely finicky, I believe you could use almost any logic board, thats made for this specific body style of mac pro(Before 2008 revision), but make sure your Xeon’s will fit the board you get. Personally, I don’t really think the logic board would have failed for no reason. I could be wrong though. Tearing out the logic board will be a long grueling process… My friend had one that need a board, and we opted to sell it over, beginning that process. I am leaning toward the power supply. I’ll look around this evening and see what I can figure out. This 06 Mac Pro has alot of life left in it, and it can be fixed. This was a very expensive machine when it was new. What gpu are you running? As a long shot the graphics card may have failed. I will do some research and get back to you, I am done w/ classes in the next couple weeks, I am completely down to help you diagnose exactly what has failed. Once you know whats wrong, the rest is easy.
Apple Mac Pro “Quad Core” 2.66 (Original) Specs Identifiers: Mac Pro - MA356LL/A - MacPro1,1* - A1186 - 2113 Just a note, make sure you have the original system installation disk as you will need the fan syncing software on it to reset it after any major parts replacement or the fans will run away. Tell us about the diagnostic lights on the logic board, please.
