Maybe you can do the following and solve the problem.
Start up the Windows XP Task Manager and select the Applications tab.
Now select the New Task button at the bottom of the window. A new smaller window will appear. In it simply type:
explorer.exe
explorer.exe is the Windows Program Manager (or Windows Explorer.) It manages the Windows Graphical Shell including the Start menu, taskbar, desktop, and File Manager. By restarting this process the graphical interface for Windows will reappear.
