In connection with the reinstallation, if you maintained some dirs like /home
on separate partitions and they were reused, it is possible that something
got screwed up and saved on them during the crash (root / deletion).

Besides that, after reading that Bugzilla discussion (post by Heinz), where
some guy (at the end of comments as I looed at them yesterday) fixed his
machine just by changing his BIOS freq to performance instead of on-demand,
and looking at my own BIOS's Power settings, with all those options having to 
do with SpeedStep (freq), thermal control, etc, I think you should try that as
well.
Besides, settings BIOS may unlock some ACPI data read by kernel that will
allow you to make the desired changes (governor, freq values) thru cpufreq
entries later on.

Another possibility is, after you update the BIOS, to reinstall F14 fresh, with
reformatting partitions, and not inheriting any separate dirs/partitions if
applicable.
Of course, make sure you do not have any problems with harddisk - after a crash
things happen.
Before reformatting partition, select disk health check in anaconda.
Install smartmontools package and run a full test.

One more - if you have space, install another distro and see if things work
there.
