Hp Pavillion 5000 notebook

Question

My hp laptop is having a bad day, we use this for business. It comes on and goes to the different type modes, I have tried safe mode all the way down to select last known working one and neither of them work, it rolls to another screen and shows the windows xp logo and gets caught in a "loop" reverting back to the mode screen again. Help.. Thanks in advance for any feedback.

my laptop wont boot up pass windows xp logo it keeps restarting at the same screen
