iMac won't boot. HD and FAN are spinning for 1 sec
Hi, When I power on my iMac I hear the HD and Fan spinning for 1 second. Then it stops and does the same thing over and over. 1 LED is steady the second LED lights up when the fan and HD start spinning. See pictures. What could be the problem? If the power supply would be damaged there shouldn't be power, LED or spinning HD and fan right (even when it's just for a second right?)
Is this a good question?
