I have encountered a problem with WinXP Pro. The boot is normal up until the OS has loaded. Then appears a pale blue screen with no icons, taskbars etc - Nothing - just this nice blue screen. The mouse pointer shows and is mobile. I am able to bring up Task Manager ( Ctrl+Alt+Del )but it freezes if I try to use it to start an application. I have done a repair install of Win XP to no avail. Pressing Win key+L brings up the login screen, showing my user name but pressing this returns me to the empty blue screen. My next step is to start in Safe Mode ( which I have tried a couple of times) and explore. If anyone has had this problem or could shed some light on a solution I would be extremely grateful.
