I recently just did a clean install of windows 2000 SP4 on my old windows 98SE HP Pavillion 6730. The OS seems to work fine with no problems but everytime I startup the computer, the mouse seems to stop working (I see the pointer but can't move it). I then have to unplug it and plug it back in to get it to work. However it sometimes does not work even after I plug it in again and have to keep repeating the process of restarting and unplugging/plugging to get it to work. Anyone have any ideas/suggestions?
