This is driving me insane. The OS has run exceptionally well since a clean install was done on October 26, 2001. However, once every couple of minutes, the hard drive is accessed. I have tried everything I can think of. Reset all paging file sizes, turned off error reporting, anything that even looks like it would actually cause a process I have shut down, but the problem still occurs. I know I am not the only one with this problem. I have seen others griping about it on the MS user groups and there still seems to be no solution to the problem. Can someone help me on this? It interferes with mouse activity, sound, everything I do. It is very frustrating. Please help.
