The comp is WinXP Home. The mouse is (was) a USB LogiTech optical mouse. The mouse worked well for some time, but it began freezing up. I could still navigate the computer via keyboard commands. I thought it was the computer and did some troubleshooting from that angle. Could find nothing wrong.
I began to think that it might the be the mouse so I tried another USB (AOpen) optical mouse. Did not work at all. So I hooked up a scroll mouse plugged into the mouse port. After the first or second restarts, I did not have internet access (which is broadband cable) and it was sluggish. After several restarts, the scroll mouse works. But now I cannot see my home network, which consists of two computers. The other computer on the network (WinXP Pro) now cannot see my computer.
Another interesting thing I noticed about the troublesome mouse was that the light would come on at odd times, even when the computer was not in use; AND when the computer was totally shut down, it would light up and stay lit for a long period of time.
Ideas and suggestions are very much appreciated.
