This is a bizarre problem. Running Office 2000 premium on a Win 2000 machine. Everything fine at shutdown. Start next day and open Word. CPU goes to 100%, Word never shows in Applications on Task Manager, Menus and tool bars are absent on Word window, although they may appear if you move your mouse over their usual locations. Remove & reinstall Office.Same problems. Anything that is in office, including IE has same problems. Remove Office, delete from registry, scour HD for any traces and remove them. Reinstall, apply SR-1, 1a, SP-3 Updates, all with the same results. Followed all advice from the KnowledgeBase, starting with /a switch, deleting Recently used file list, etc. same result. Any ideas other than Fdisk and start over?
