Mouse (not responding)  

It says (not responding) when you click on something with the mouse in firefox browser? or programs, games etc? You have to click multiple times to enable programs to respond? First and foremost, you need to check if a driver is missing and if not, go into the application compatibility and make so that older programs will run on your Windows version. I guess you must have Windows 7 for this to work. This worked great for me. I never thought this would work but it did! Good luck and please write back if this worked for you.
