Is there something that can kill a power supply?
I have a mid 2009 27” iMac that had a dead power supply, it died back in July of 2016 and I never got it fixed because I was quoted 700+ dollars.
Finally, I just ordered one from amazon and my husband put it in using the IFIXIT guides. It worked perfectly for 8 days than starting making this weird buzzing sound.
The next day my power in the room went off (never happened before) and the iMac won't turn on now -_- 2nd bad power supply?
How does that happen? Was it just a bad replacement or is something in the iMac killing the power supplies? They are replacing the part but I'm scared to put in it and have something ruin it!
