Half a chime then shuts off - boots after a few tries or unplugigng
I'm working on a 24" 2008 iMac that has a weird issue where it takes a few tries to get it to turn on. Once it is on, everything seems to work fine, but it takes a few tries to get there. It'll usually do about half of the chime then immediately shut off.
Could this be a power supply problem? I found a similar issue on these forums and the answer was a GPU replace/reflow.
Это хороший вопрос?
