I have the HP Media Center PC m7250n. My problem is that the computer hangs at the blue HP screen on startup. The computer does not shut down completely without manually pressing the power button on the front. If the equipment is left in your car is turned off (or attempts) and requires the button is pressed again. The center of the media simply will not work and left me the error message if I could get the blue screen. Any help would be helpful, but do not give me "buy a new computer" response. I'm already stressed enough.
