Mac Pro Power Supply dead?
Mac Pro 2.66 GHz Quad-Core Intel Xeon
For the past 4 months my Mac Pro 1,1 quad 2.66 has been crashing. I replaced the ram using the specific fully buffered ram, in a pair etc. Blew out all the dust from fans and power supply with a blower. running smoothly all day and left it running overnight. this morning found it to be dead.
when i press the power button not a single light on the logic board comes on, no fans starting up or electronic noise.
i tried to reset the SMC and the button above it on the logic board with no result. removed the graphics card and tried again. took out the optical drive to find incredible amounts of dust so once again blew all that out and blew air through the power supply and sent dust all over the room. plugged it back in and no result. With everything that i have read i think it has something to do with the power supply. could it also be the tiny flat battery on teh logic board prehaps short circuting the system? If it is the power supply is there just a fuse blown that i can replace? Also if i put my ear right u against the power supply when its plugged in i can hear a very very faint ticking sound, similar to perhaps the sounds ignition sparks make on a gas stove.
I dont want to take it into the shop and pay the $70 odd dollars to just have it diagnosed if it is such a simple asnwer so can anyone please please help me!!!!
Ist dies eine gute Frage?
