Strange crash with shrill noise - anything to worry about?

Question

A few minutes ago I was moving my cursor across the screen and accidentally clicked on the garageband icon in my dock, which I haven't used in over a year. The program goes to load and while it's loading, my computer starts emitting this loud, shrill sound while freezing up. It allowed me to open a few new windows but as I was trying to force quit Garageband (which eventually loaded up), the computer froze. I turned it off and it seems fine now but it was a strange incident...anything I should be worried about now?

Hi Jiggymike!
Run Repair Disk.
THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
1.Insert the System Install disk, Mac OS X CD-ROM disk, or Restore DVD disk, then restart the computer while holding the C key. Use the System disk, of the OS, that is currently installed.
2.Once started up from CD or DVD, on the Menubar at the top of the screen, choose Disk Utility from the Installer contextual menu for Panther, or Utilities for Tiger.
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc to access Disk Utility.
3.Click the First Aid tab.
4.Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5.Select your Mac OS X volume, if necessary.
6.Click Repair. If DU reports errors it has fixed, re-run Repair Disk until no errors are reported.
7.Repeat steps 5 & 6, but select the Hard Drive this time. It's usually the first listed with the manufacturer's model number. Make note of the S.M.A.R.T. status.
8.When finished, select Quit Disk Utility from the Installer menu.
9.Select Quit Installer from the Installer menu.
10.In the resulting pop-up window, choose restart.
11.After the computer has restarted, you can eject the CD.
You should also run the Apple Hardware Test.
Post the results.
