Using iMac OS X 10.5.8 A few days ago, when I tried to login, the system accepts my password, goes to a blue screen and then goes back to the login screen again. I tried a few times but the result is still the same. I cannot get pass the login screen. I tried the following using the Installer Disk: -Use the Disk Utilities to Repair Permissions and also use Disk Repair. -Perform a Hardware Test. Result given is 4MoT/1/40000003: HDD-1327 I read from somewhere that it means that the fan is not working properly? Does it mean that I cannot login because the fan is failing? What else can I try? Thank you for all help!
