XP won't Start - Getting looping message

[dah]

I had a program crash and shut off my computer. Now when I turn it on it looks like it's booting up and going to start windows XP then it goes to a message that tells me because of some type of failure the computer needs to be restarted. I then get the options of starting in safe mode, last configuration that worked or start windows normally, then it counts to 30 sec, then looks like it's going to start but then loops back to the message?  

It doesn't matter which I do choose, my system then loops and then takes me back to the same message.

Good ole tech support has the same answer as always, use the restart disc wiping everything out on the computer. :-/

Can someone please help? Thanks

Do you require help with erasing your hard drive data? I suggest you create backups first by setting this harddrive as a slave on another computer.
