Sorry to hear that.

We're going to need to know which startup scripts have the FAILED. They
might be causing this problem, and should be investigated in any case.

Yes. There are a number of ways to do what you want: the easiest is to
edit /boot/grub/grub.conf. There will be a stanza looking like this:
title Fedora Core (2.6.5-1.358)
kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/ rhgb quiet
Change the kernel line to
kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/ 3
(If you've installed updates, which is a good idea, then the 2.6.5-1.358
might be a different number. Leave that alone: don't try changing that
The change does three things: it turns off quiet mode, showing a lot
more diagnostic text on boot-up; it turns off the Red Hat Graphical
Boot: you'll get the text interface you described every time, and it
turns off the automatic loading of X (runlevel 3 is just like runlevel
5, but it doesn't start X). To get into X, log in using text mode and
type startx. This command line
startx > startx.log 2>&1
should keep X diagnostic output in a log file named startx.log.
Hope this helps,
