I'm running Win 8 and suddenly one day to another my mouse stopped working i thought that my mouse was dead because it was really used so i bought a new one but it didnt work either, i dont get a mouse name under mouse hardware or under device manager, its blank, i really believe you guys could help me, I've tried several solutions from these website and none of em work. If it helps i use Genius wireless mouse 2.4Ghz. Both of them, old and new, different models.
