My computer is a hp media center pc m7250n. My problems include: 1.freezing on blue hp screen on start up. 2. The computer wont shutdown completely without a manually pressing the power button on the front. 3. If the computer is left on it auto shuts down (or attempts to) and it requires the button to be push again. 4. The media center just doesn't want to work and I would put down the error message if I could get by the blue screen. This computer has seen its fair share of problems its had the power go out when nortan anti virus is running, it anti virus live was accidentaly downloaded but im pretty sure I got rid of that. Any help would be helpful, but don't give me the "buy a new computer" crap. Im already pretty stressed already.
