Thanks for your suggestions. I have looked through /var/log/syslog and
there doesn't appear to be anything in there.

I have also tried running the memory test, but it froze during that,
though interestingly the + after Memtest (in the top right, with green
background) still flashes!

So the power supply it is!

Once again thanks everyone for their help & suggestions.

If that doesn't turn up anything, run the memtest utility

burn yourself a cd with that on it.) If it shows errors that's
likely your problem. If it dies doing that, suspect the power supply...

It's actually an option during a normal boot. Hit ESC at the Starting
GRUB prompt and select memtest86 from the menu:

From the installed /boot/grub/menu.lst:

title Ubuntu, memtest86+
root (hd0,0)
kernel /boot/memtest86+.bin
boot


Well gosh darn it - it is so!
Thanks for pointing that out!

Hi Jamie!

If it were me I would:

0. Reset the CMOS values to defaults (factory or latest ROM). Without
turning the computer off see if it runs OK. Sometimes the CMOS
battery gets close to death and the CMOS is actually corrupted but
does not know it so things get flakey. If it runs OK replace the CMOS
battery and make sure the holder is clean.

1. Place the disk(s) with the music archive on another computer and
copy them (save what is important first). If they are also the boot /
Ubuntu disks migrate to the /var/log directory and copy messages,
dmesg, kern.log, Xorg.0.log and run "tail" on any you see that look
interesting as well.

2. Boot Puppy, Knoppix, or another distro of your choice live and do
thier memory test - if ok - then do an "lspci > lspci.test" and copy
the resulting "lspci.test" file.

3. Just a hunch, if the memory checks out try replaceing the video
card with another to test. It may be best to run the first tests with
live CDs.

Good Hunting!

Tod
