Hope this clarifies things. It works well for about an hour or so and then freezes up. Once it was like a screen coming down with a ticking sound. Scary! Thanks for your help.
Unless you installed some nasty piece of new software recently, and coupled with the ticking sound, I get this queasy gut feeling that your drive is circling the drain.
Besides immediately backing it up, just in case, open Disk Utility, select the DEVICE (not the Macintosh HD volume) and check the S.M.A.R.T status on the thing. Anything different from "verified" is cause for concern, and should cause you to jump off your butt and go about procuring a drive replacement PRONTO. As in yesterday.
