When it was starting a couple times a day. I will keep thinking of things you can try while you are waiting for the MacRunor folks to reply. power light comes on and fans turns but that is about it. I have a dead macpro hear - older 1,1 model that i am trying to get to run for a friend. if you hear the 1st chime hold for 2-3 more. can you hear the computer chime when you startup. I tried each memory stick in slot 1 (only 1 stick installed at a time)ġ) hold option key when starting - does the Startup disk window come up ? if yes, how long does it stay up ?Ģ) hold shift key when starting - does computer startup in Safe Mode ?ģ) Apple Option P & R Keys. I re-seated the HDDs, Memory, Video card, CPU, PSU connector, and checked all the other connectors. Today it tried to start then clicked off instantly. today and yesterday it would only start one time after sitting overnight. A couple times it started up when I plugged in the power cord (I did not push the power button)Įvery day for the last 4 days it starts fewer times. and on start up 2 Red LEDs flash on the top left motherboard. Even with no mouse, keyboard or monitor plugged in it shut off after 3 min. Then shuts off after about 3 minutes or less. I am able to open and navigate through the software. When it starts it boots perfect and performs fast and smooth. It will only start 1 or 2 times a day and will shut off on its own after about 3 minutes. shipping will cost about the same as a new machine. so shipping it back to the USA is not really an option.
