Every once in a while, when I am in Win98SE, my keyboard and mouse simply cease to function. My computer isn't frozen, the rest of the processes continue to run, but my mouse and keyboard stop responding. At first, I thought this could bea motherboard problem, until I realised that this doesn't happen in WinXP, so it must be a software problem in Win98. I have the newest drivers of the two, a Microsoft Internet Keyboard Pro, and a Microsoft Optical Intellimouse. They both cease to respond at the same time, and again this only happens in Win98SE, and not WinXP. Thanks for the help that comes from this site, as it's helped me do a lot of things in the past regarding fixing my computers, and has even helped me fix other peoples computers! TIA for all the responses from you knowledgeable people in this forum!
