white screen no logo start up noise then clicking
My 2009 iMac has a big problem. on turning the power on the deep base boot noise sounds, the screen goes white but the logo does not appear. There is then a loud repetitive clicking noise from the iMac.
The 4 lcds on the motherboard are all it. The hard drive has been replaced as I originally thought this was the problem. Sadly the problem remains.
Prior to this problem, the DVD drive has intermittently stopped working, and then completely ceased working but the machine has always booted normally and performed well with an external DVD.
Can anyone help?
