I have rh 7.1 installed, working fine until this morning now i cannot log in

I set it for level 5 so it boots into xwindows now its started going funny making it impossible to use. what do i do
to get back the system

help please

quite easy.
boot into Linux at initlevel 1, by adding "rescue", "s", "single", or "init=/bin/sh" at the bootprompt. This will bypass logging in, and land u at the prompt as root. Now edit /etc/inittab and set the default initlevel from 5 to 3.
reboot, done.

when lilo loads, hit ctrl+x... then type '<linuxLabel> single' (NOTE that you must replace <LinuxLabel> with whatever label your LinuxBoot is named...

then you will go into textual mode... if you would want to keep logging in in textual, I would advice you to edit the inittab file (try "locate inittab" or "whereis inittab"... I guess you can find it in /etc ...)
Use (assuming you are in the folder of inittab) vi ./inittab and edit the file... you should find a place where something like "dd:5:blablabla" or something is located, change the 5 to a 3 and you will startup using runlevel 3 always (if you have no network, try 2 instead of 3)
