I tried starting my iMac and all I get is a light colored screen and a beeping sound about every 5 seconds. No sound from the drives. How can I get it to turn on?
iMac, Mac OS X (10.6.3)
That usually means there is a memory problem. Either no memory or bad memory doesn't pass the power on self test (POST). See http://support.apple.com/kb/HT2538
You can try reseating the memory, using 1 card at a time, swapping the slots the cards are in, or getting other working memory to try in your system. If all of those fail, then take it in for service. See http://support.apple.com/kb/HT1423
Thanks! I had added memory a couple of months ago. Took out the original memory card and replaced it with the newest one. It works, but slower with only part of the memory. Will need to order another.
When I turn on my iMac, I get a light colored screen and beeping about every 5 seconds. Running Snow leopard. How can I get it started?
