The system seems to think that it got shut down by a power failure or
something of that nature.  Try booting again, but when you see the
"Press Y" prompt, press "Y".  The system will attempt to do an fsck on
your root drive (the one with the "/" filesystem).  If it finds badness
on the drive, it will try to repair it, but be warned that you may lose
some data if it finds the disk corrupted.

If pressing "Y" doesn't work, verify that the keyboard is functional.
Press the CAPS LOCK key and verify that the LED lights up.  If it
doesn't, then you may have a hardware problem.  It could be a bad
keyboard, a bad motherboard, bad memory or a bad power supply.  If the
keyboard works at the BIOS prompts and such, then I'd try to boot off
the first install CD and at the "boot:" prompt, enter "memtest86" to
test your memory.

If the memory passes the test, then I'd start looking at the power
supply.  If you know how to use a multimeter, check the power levels.
You'd be amazed at how flakey a system can get with a bad power supply.

Hi Rick.. Thanks for the help. I did a

# rpm --rebuilddb

and that seemed to correct the problem. However, when i did it I forgot
to remove the "__db*" files.  Should I have removed them first ?
Everything seems to be working fine now I can install or update via rpm
and yum, but I wonder if perhaps I should still do a

# rm -f __db*
# rpm --rebuilddb

or should I leave everything alone at this point since it is working ? I
am inclined to leave well enough alone at this point and go through the
3 steps in the event I experience such problems again.
