Hello I'm Karen and new to this forum. I used to have fairly longish hair but now I am totally bald due to pulling it all out recently when my computer left me. Basically I've pressed so many buttons on it that it got sick and collapsed. Okay, when I turn the computer on it comes up with 'tetris' but not the game. Then it looks as though its going to open up, i.e., the blue screen appears and then the window with the light reflection and then that is it. It doesn't continue to welcome me or proceed to the main desk top icon screen. The only thing it displays is a box with performance manager written in it and it looks like a hospital heart beat monitor. I really am stuck. Any help would be greatly appreciated.
