Am running Win xp on an oldish desktop . At recent switch on, everything looked same as usual but, when boot-up completed, wireless mouse had stopped working. Pointer would not respond. Had been using this wireless mouse for some time with no problems. Tried an old (none USB) cable type optical mouse. Plugged into correct socket. No better. Mouse still did not work. Pressed various keys (ALT etc.)and managed to access control panel then Mouse settings. This said that cable mouse was working correctly. Sadly it wasn't.
Still having no success! Thanks Woody and Fruit Bat. The wireless mouse came with a USB memory stick. All I had to do was plug it in and away it went. No probs. Worked fine for long time until failure. Then tried all kinds of things but. without the mouse, very difficult.
Installed another copy of the same Windows on a different drive. It worked perfectly, wireless mouse included. The old cabled mouse did not work on the new Windows therefore dumped. Sadly I am now going to have to spend a lot of time getting access to all the things that were on almost instant recall with the old windows.
It sounds like the old windows has the mouse driver damaged.
I know you did not load one but there has to be one .
Have you checked in device manager?
I would have a go at repairing old windows but make sure you have backed up before you do much.
Through Control Panel select System, Hardware, and device manager. In Device manager select by double clicking or expand with the '+' sign, Mice and other pointing devices. Highlight the device that you have then right click and select uninstall. I know it is difficult to navigate via keyboard but with the TAB key and the arrows keys, enter etc. you should be able to do it. XP will reboot twice with the USB receiver still plugged in to your PC and will install generic drivers.
