download this & install it

 

after restarting your PC check if it works...

otherwise Uninstall Synaptics Touchpad Driver

 

try this

Please ignore last EverWin post.

 

Go to Control Panel -> Devices Manager

Click with right button of Your mouse on each yellow sign and choose properties. Then go to bottom details and paste here Hardware Ids. This way we will know what it is.

 

Below You've got example how to do it:
