HP Pavilion DV9000 Notebook keeps rebooting with dead Screen at startup

Whenever I push the power button on HP Pavilion dv9000 Notebook, the display doesn't turn on plus the notebook shuts down following 2 seconds. Behind a few seconds of high-pitched sounds, it automatically turns itself on as well as shuts down over again. The procedure repeats itself again and again.
