Several months ago I bought a new Gateway system with XP. It came with a Logitech mouse which I installed and used up until a couple weeks ago. Then I decided I wanted to use the cordless Logitech mouse I had on hand so I installed that. I connected the receiver to the mouse port with an adapter and had been using the cordless mouse with no problems until yesterday when it suddenly stopped functioning. Can an adaptor or a mouse port suddenly "go bad"? Does anyone have any idea what's going on here? The short answer is yes. But I think it is unlikely. Several suggestions to try and isolate the problem. 1. Try a different Mouse on the Same port. 2. Try the Problem Mouse on another Computer. 3. Try re-installing the Mouse Driver. But un-install the old driver first, as you are having problems I strongly suggest you do this via Safe Mode. To get into Safe Mode Re-boot your machine keep tapping the F8 function key as the machine is starting. You will be presented with a multiple choice menu. Somewhere in the middle will be a choice of Windows Safe Mode. Click Ok to get to your Desktop, Click on Start, Settings,Control Panel. Click on Add & Remove Programs Icon, find the mouse driver and click on remove. The reason so doing it in Safe Mode you are more likely the remove all of the Driver files opposed to in normal Windows. 4. Windows itself could also be the Culprit.
