This afternoon, in a rush of blood to the head, I updated my Logitech QuickCam software. What a mistake! Not only did it not work, I couldn't uninstall it and had to revert to going back to yesterdays Restore point. All well and good, except that now, all my Sound, Video and Game controler drivers have the dreaded yellow exclamation mark against them. In spite of re-installing my sound card driver five times this afternoon, the yellow peril still remains and so I have no sound. I can see that I am going to have to step into the registry - a scary thought. Does anyone have any other bright ideas or suggestions? Would a proprietary Registry cleaner help?
