A little over a week ago, I was merrily computing away when I discovered that some of my basic functions (Recycle Bin, My Computer, My Documents, etc.) have disappeared into cyberspace. Any attempt to access any of these functions results in a complete computer lock-up, and the only way I can go on is to power down and do a re-boot. Has anyone ever heard of this? If so, is there any solution for the problem short of trashing my computer and starting with a new one?
