I'm using Microsoft XP Pro, al was fine until yesterday when I turned the computer on and it looked a bit blurred. When I shut the computer down everything goes fine until the monitor normally shuts down. The on/off button on the screen normally turns from green to orange to show its shut down, instead it stay green and the screen turns completely red, then blue, and cycles through a number of different colours, but never turns off. How do I fix this?
