I am getting a strange problem in Windows 7 where my mouse stops working randomly from time-to-time. I hear the 'device unpluged' sound (the dee-doop the the computer makes then you remove a USB device) and the mouse stops working for about 3-5 seconds. It is very irritating. I have tried Binging the problem but have found no fix on Bing or Google. I have also tried several mice including a MS Sidewinder, Dell optical mouse, NZXT Avatar and MS wireless mouse in different USB ports on the PC and they all seem to work fine. Is this the resault of some sort of Virus or is a Microsoft bug.
