Logitech Wireless Keyboard & Mouse Stop Working
 

Hello all.
I'm after some help. About a week ago my mouse and keyboard started to stop responding at random times and the only way to I can use them again is to reset my machine.
I have also lost the use of the scroll wheel.
My mouse is a MX700 model. (USB) It has a USB receiver that plugs into a USB port and the mouse & Keyboard talk to that.
The only thing I have done which may have caused this is installing the latest Nvidia graphics drivers.
I am using Mandrake 10.1 OE
Any help would be greatly appreciated as Linux is Unusable at the moment & I have had to go back to Windows.

Update: My Keyboard & mouse work fine with Knoppix & Windows XP.
