Mac Pro (2006) Power supply/replace
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
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
can anyone help :) im not sure what to do
