I am running WinXP Pro, Cable (road runner)

My pc was running fine today and I turned the pc off (I did not shut down properly, I unplugged it) because a lightening storm came up quickly.

Now when I try to start back up the pc I get a screen that says
the pc did not shut down properly and here are my options:
SAFE MODE
SAFE MODE w/networking
SAFE MODE w/command prompt
LAST Known good configuration
or
Start Windows NOrmally
I tried all of these and the pc keeps rebooting. Any ideas?
Thank you in advance for any help.
