Problem after change cpu ram and ssd
Unfortunately after changing out of the CPU, RAM and SSD my iMac does not restart any sign of life just a green LED on the motherboard,
I don’t really know what to do, I have everything back, I'm disappointed Do you have any idea what the problem is?
For the moment I strongly advise not to make the change of the CPU and the RAM : /
Here’s the picture of the motherboard
