I have got a desktop system , I like to play games on my system , since a few days my system is behaving quite odd. This is all happening after I have installed the Windows 7 , prior to this I was using Windows xp operation . I used to play my all the games in the xp operating system. After upgrading to the Windows 7 , my mouse behaves in a funny manner, its pointer stutters and freezes in between and suddenly stops working. To make it work I have to restart the computer. I have got a Logitech mouse. Please help me in solving this issue as it is very annoying and I am tired of my erratic mouse behavior.
