No boot, black screen after cpu change
After I changed the CPU on my iMac 2010, from i3-550 to i7-870, I get a black screen. I hear the fans turning on and off continuously. I have tried to go back to the i3-550, but it’s now the same issue, whether I boot with the i3-550 or i7-870.
Thank you in advance
