XP crashed after attempting to install a digital camera

[Guest jcwinters]

Was instructed to restart the system. I restarted the system and a blue

screen with an error message flashed for a second and the system moved the

DOS screen (for 30 seconds) that normally allows the user to move into Safe

Mode, Last Good configuration, etc. Was not allowed to move the cursor with

arrows and then it continuously moves to attempt to normal start-up and then

returns to the same process, over and over.

 

Please help
