Your first recourse is to open a terminal and run dmesg. It will show you boot mssages. If there are errors, they may give you insight into the problem. The list may be longer than one screenful, so pipe the result through less or tail to reduce the amount of file to view at one time.
Examples: dmesg | less # will scroll one page at a time as you press the space bar. also allows you to scroll up and down through the output of dmesg.
dmesg | tail -n 100 # will show you the last 100 lines of the boot message file. can also be piped through less: dmesg | tail -n 100 | less
Look at the logs in /var/log. You have boot.msg, localmessages, as others to peruse for error messages.
