I have windows 98 SE operating system and when I boot up the desktop appears and all the icons on the desktop appear. The cursor will move around on the desktop with the mouse but clicking on an icon has no effect. None of the programs in the startup tray load (on right side of Start bar) nor does outlook load. Ctrl/alt/del combination does not work, the only solution is to turn machine off and reboot. USUALLY on the 3rd or 4th reboot it will boot normal and load all programs including Outlook.
