When I boot the computer, it brings me to user profile page that displays correctly. When I chose a profile loads and the screen is blank other than the desktop wallpaper. No Task bar, start button, icons, nothing but wallpaper. The only way to access the system is through control-alt-delete and choose "new task". From new task I can access all programs, even can choose desktop and it shows the desktop icons that you can open. I tried reloading Win XP Home Edition but get a message that there isn't enough disk space. I tried Disk Claen-up and Disk Defrag but it dosen't solve the problem. Any help will be appreciated.
