PSU, or rather the motherboard?
I encounter something I'd like to have your opinion for…
A morning, I found my mid 2007 iMac off after having let it on at night.
The power button didn't work neither, nothing happened.
I opened the machine, and played with the diagnostic LEDs.
What I happen is somewhat weird (I think). The first-left LED gets on on plugging the AC cord, After 3 or 4 seconds, all the LEDs flash and then… nothing, strictly nothing.
Do you guys think it could be the PSU, or rather the motherboard?
Thanks in advance!
Is this a good question?
