good. Short summary: firefox + flash + nvidia = nightmare, while
kde/gnome quirks make things more... interesting.

Good morning, everybody!
I just woke up and found lots of other suggestions, both here and in
20/30 comments on the web page, which I just approved so are now
readable by everybody.
Almost surely, today I won't be able to try and report about the
latest suggestions. I have to leave with family in

Sorry, wrong OS. Use smartctl, which is part of the smartmontools. Look for
reallocated sectors, which is a bad thing...

smartctl -a /dev/sda

AMD's Socket A. Pretty old, slow system. It's possible it doesn't implement
APIC and ACPI correctly. Someone suggested a bios update - if there is one,
that would be a good idea.
Does the command 'smartctl -a /dev/sda' show any reallocated

So you've got the Nvidia stuff loaded - well an obvious first test would
be to run with the provided Fedora Nvidia drivers and X. That would be a
quick way to eliminate one possible cause.

Firefox open. when there is REALLY n
