My iMac has a black screen
I was replacing my CPU to an intel i7 870, when I put I back tougher the iMac didn’t turn on. So I put back my original CPU I hear a boot sound but no screen image.
I have tried to reset the PRAM and the SMC but its not working! I think I broke the graphics card but I’m not sure.
Please help me!
