My PS2 Mouse does not want to work on Win 7. I reinstalled Windows 7 3 times and still my mouse does not want to work, PS2 keyboard works fine.
Windows boots up and then I can only use the keyboard.
What do you mean by install it?
What is the model number / make and does it have weird functions?
I have never had a problem with bog standard PS2 Keyboard / mice and have never seen a problem with Windows with them:S
All I can really say is check the connection and if through driver you mean it is some weird wireless model with extra functions, try re syncing it with the base as the settings may have been lost.
