IMac Freezes on Restart

Question

Hi Everyone,
I have a 3.06 Intel Core 2 Duo iMac with Snow Leopard. It is completely up-to-date and has always ran beautifully. I have not installed an new programs lately.
Recently, my computer began to slow down a bit and now when I go to APPLE > Restart (maybe after an update or just because I like to restart my computer on occasion) the bar at the top disappears, my dock stays up on the screen, and the computer just sits there and freezes up on me. I am forced to hold down the button on the back to get my computer back.
Any idea's? Thanks.

Hi - how did you do your update to 10.6.5, via software update or using the combo?
Sometimes a few people have problems after a major update to the OS and often re-applying the update using the combo updater: http://support.apple.com/kb/DL1324 will resolve odd behaviour.
It's often advised to 'repair permissions' before and after a major update - Utilities>Disk Utility, select your Macintosh HD on the left and click on 'repair permissions'.
If any of this resolves the problem I'd be inclined to check my HD is all good by booting from the install disk that came with the Mac and doing a disk check. Disk in DVD/CD drive and restart holding down the C key, select your language at the multi-lingo screen and at the next screen from the menu bar Utilities>Disk Utility, click on Macintosh HD and select verify/repair. If it reports some things were fixed run repair again until you get a clean pass and the restart as normal from the Apple menu.
