OSX Hangs on restart

Hello, everyone! Ever since the most recent security update (as of June 4, 2011), my iMac (2.8 Ghz Intel core i7) freezes on a blue screen during start up when I have my USB peripherals plugged in, as well as my Firewire Time Machine drive. The only way I can get the iMac to successfully start is by unplugging everything, starting the computer, and then plugging the USB and Firewire externals in. Has this happened to anyone else, and how can I resolve it?


Thanks!


Joe

iMac 27" Intel core i7, Mac OS X (10.6.4), 8 Gb RAM

I would boot from your install DVD and run both Disk Repair and Repair Permissions.



Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.

When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)

Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.

Click the First Aid tab.

Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.

Select your Mac OS X volume.

Click Repair. Disk Utility checks and repairs the disk.
