Not sure why the iMac isn't booting
My friend gave me a imac emc 2133 to try and fix. He said he thought it was the power supply but when I plug it in it does turn on for a bit and nothing else. When I hit the power button the screen goes white and makes the chime noise but after that it goes black again and nothing else happens after that. What steps should I try for troubleshooting this device?
Is dit een goede vraag?
