Extremely slow startup on iMac

Dear All,

I have posted similar problem about my iMac (early 2006) few weeks ago, about slow startup on my iMac due to some fonts problem and the problem was gone after ~Bee advice me.

However, the joy does not last. Last week, I have installed CS3 (only Illustrator and Photoshop with Bridge) into my iMac. Things are doing great last night except this morning, when I switched on my iMac, the loading blue bar was crawling and stopped in between before it reaches the end. After everyting was loaded, I used Disk Utility (boot from Apple CD) to verify the permission and towards the last 20%, the application seem to stopped. I waited for 20 minutes and the status still the same (remain the last 20%). This is very unusual coz normally, this process was only take about 1-2 minutes? So, I have cancelled the Disk Utility and shut down the iMac coz I need to go to work..

Before I shut it down, I also used Onyx to scanned my iMac and at verification process, the software gave me Error -1. What does this means?

Can anyone please help? Any suggestion? 🙂

Thanks so much!
