fan runs but wont start up
G4, dual 1.25, M8570
when trying to start
one fan starts, after five seconds a second much louder fan starts and
thanks for the images !
I would say that this is quite obvious a processor failure.
Try a replacement CPU Card - check the LogicBoard from both sides for any suspicious singns of burn damage (brown or black color w/ smoke marks) in close location of the CPUCard connector. If you see no sings of that just put in a replacement CPU card and give it a try.
no chime sound,
monitor no reaction,
I took off the heat sink, and the top of the processors looks brown, and minimal thermal compound on it,
should I put new paste on it,
is this causing the chip to heat up and put the 'super' fan on?
you go to the toolbar in the answer box where its reads "Insert an Image"
press the "Images" tab below , upload, and drag the image in the answer box above.
A G5 is faster, but this is iFixit - and a new CPU card or a LogicBoard is just a few $ on our beloved electronicbay.com auction site.
Let's have a look at those images !
This FAST FAN and NO START UP also started happening on my G4 but ONLY after I left the air condtioner running in the office at night.
This problem is some how COLD related. When I heat the office it works fine and starts right up. Any one noticed this issue with COLD??
