It stops responding to *most* mouse-clicks and keyboard input, in particular those trying to switch programs, or apparently anything that needs disk access.
A short "Blip" sound is given off now and then - shorter than the standard beep, as if it's been chopped off. Repeats every so often, maybe 45 seconds, but I haven't timed it, and I couldn't swear it's regular.
The HDD light (leftmost of the lights above the keyboard) stays on solidly.
It won't respond to <Ctrl><Alt><Del> - the only way to get things going again is to power-cycle it by holding down the power button. It powers up OK and will run fine until the next instance of this problem.
On one occasion (only, out of dozens) there was a repeated "clunk-whirr-clunk" sound from the disk drive until I powered it down.
Because of the latter and the HDD light, I suspect my hard drive is failing (it's a 30GB Travelstar, vintage Dec '01) but I'd like others' opinions. This doesn't happen to a regular timetable, but it feels like it's getting more common, and now happens about once a day.
Oh, and I *am* doing regular backups!
Cheers,
Howard
