Suggest:
Boot with an install CD/DVD in rescue mode.
Mount your file system (this should happen automagically)
edit /mnt/sysimage/etc/inittab
Set your default runlevel to 3 (currently it is set to 5)
quit the rescue, and reboot your hard drive.
 
Now you will have the shell available to debug what goes wrong when you
command 'startx'
