Hi,
I have a iMac A1418 board 820-00034, the problem is when the board is cold i can get to the mac os log in for like 1 min and then start the bootloop, but is a fast bootloop sometimes i can just see the apple logo for 1 sec and keeps doing it until i un plug the power, if i try to turn on again the bootloop continues, if i let the board un plug for 15 or 20 min i can turn on again and log in on Mac os but the bootloop start again under 1 min.
I try to get to the recovery and i can, when try to install a new mac os it starts loading the usb and then start the bootloop, but if y left the recovery on the boot selection it can start on no bott loop until i select the HDD or the USB drive, i try to change the thermal paste just hopping is just overheating but no luck, i am clueless what can be at this moment, i think it is a power issue, because if i turn on the board w/o the screen connected it let me log in and stays on but because the screen is not connected the fan is a 100% and the cpu keeps the lowest frequency is supper slow.
Any help will be appreciated
