Thoroughness does have its advantages.
I'm going to do that from the Knoppix cd I have, although I'm not sure
how to do it? Do I chroot into the partition, then run fsck?
You don't have to chroot. Just boot into Knoppix and run fsck on the
appropriate unmounted partition.
Basically, I think the problem is Opera and not your system, X server
or otherwise. Your system ran okay until you started Opera, right?
Did you run a checksum on the Opera download before installing it?
Have you updated/upgraded your Etch install, so that it has the most
current libraries, kernel, etc?
I wish it was only Opera. The system has crashed three times today, or
maybe four, I'm losing count.
Okay. Definitely NOT Opera. It could either be hardware or OS.
At the console (without X running), I ran
memtest 128m --log (maybe a dumb move, as I only have 128mb of ram)
and the system rebooted uncleanly.
Try running memtest from Knoppix and not from your installed OS. Or
better still, go into BIOS and set it to do a memory scan before it loads
any part of the OS.
In X, I was running Firefox (Iceweasel) and the system rebooted
uncleanly.
More evidence of a hardware problem. Test the voltages on your power
supply leads to make sure they are outputting the proper voltages.
I did some work on the machine--cleaned all the dust out of it, took out
the winmodem that I don't use, went into the bios and disabled the
parallel port and 1 serial port that I don't use, reseated nvidia
geforce graphics card and jiggled wires.
Then I booted the machine, started X, played some bzflag, ate dinner,
and when I came back I saw the login prompt, but this time the system
had rebooted *cleanly*, while I was away eating. At 20:14. Strange.
It shouldn't have reboot at all, cleanly or otherwise.

Problems like this sometimes take weeks or months to solve and rectify.
Just eliminate each possible problem one by one.
So far, I don't seem to be making any progress and things are
deteriorating, as in "getting worse."
If your RAM checks OK as well as the power supply, consider reinstalling
the OS on just / and not /home. Corrupted files, which won't show up on
a fsck, could be causing the reboots.
Have you check to see if the kernel was or is damaged. Or just install
one whose checksum is good. Of course, you could have corrupted
libraries, etc. or your hard drive could be slowly failing, which is a
good possibility, if the hard drive like the system is 7 years old.
It's the same stock debian kernel 2.6.18-4-686. I don't know why I got
a kernel panic. I don't know how I'd check for corrupted libraries,
either. smartctl finds nothing wrong with my hard drive.
Only way I know of the check for "bad" files is to compare them with
known good files by checking file size, checksum both, binary compare.
Well, assume the HD is okay, and reinstall the OS, then you know all your
files are good. Checksum the install CD to make sure it is okay before
installing. Worse that will happen is the same thing.
I had a similar problem with my old system, except it didn't reboot, but
just turned off. After months of trying things, discovered the CPU was
bad. Replaced it and haven't had any problems since.
