Need a bit more info here. What happened before the system died? Where you working on it and now it won't start?


It just stopped working, one night i turned it off and the next day it didn't work again.

If it won’t power on at all its the power supply, replace it and you’ll be fine.

If it’s one of the most common 2011 iMac 27” failures-it’s the vga card not easy at all.
