Hello everyone, I have a 17" Intel iMac (late 2006) and I've noticed that the speed of the iMac went down. If I press the power button, it takes about 3 times longer than normal to boot the system. Programs also start very slowly. I think there's a problem with the hard disk but even the Apple Hardware Test CD says that everything is ok. I tried to format the disk but it also takes very long to do this. Now I'm installing Leopard again but it takes about 5 hours to do this.. Could I be right about the hard drive? I've heard that it's difficult to change the HDD in the 17" iMac.. Thanks!
