Boot problems! Will only start up after the third attempt?
I have a weird issue with a 24" Imac. When I plug the computer in the first diagnostic led is on when I press the power button I get 3 lights hear a half chime and it stops. All lights go out including the first light. I unplug it plug back in 1st light comes back on, press power and get 3 lights again and the half chime all go out.
The third time
I unplug and re plug again 1st light comes back on but this time it boots right up all lights full chime and screen comes on.
At first I thought this was a power supply issue but wouldn't the first light stay off when I unplug it a re plug in if it was the power supply?
After I get it to come on the third time, I can turn it off an on normally until I unplug it and let it sit for a while. Then I have to do the 3 time unplug deal.
I have replaced the Pram Coin battery, and reset the pram.
Any Ideas what might be causing this?
Is this a good question?
