I am working on a computer running Windows XP Pro. When I turn the computer on it will eventually activate the monitor. However, only the wallpaper appears...no icons, no start menu, no taskbar. I can right click and get to the (Arrange Icons, Refresh, etc) dialogue box, but I can not access Task Manager. I also cannot boot into safe mode. I can't even get to the alternate boot screen to select safe mode. I click f8...as well as trying other keys as well...and the system just ignores it. I get no beeps at all. One other weird thing...the computer will not turn on with the cmos battery in. And when I put the cmos battery in after the computer has started...it turns off. Can someone give me a suggestion or two...I hate to admit it, but I'm stumped. Thanks to anyone who can help.
