I have a lenovo 6GB ram pretty standard desktop PC. About a year old, came with Win 8 and worked perfectly until......
8.1 upgrade. Didn't even know it had upgraded until it asked me to restart???
All seemed ok at first... After a couple of days my mouse, again a pretty standard old Dell optical, began to take on a mind of its own?
It highlights vast areas of my desktop whenever it feels like it, opens up the display menu as if l had right clicked (does this most of the time).
I am unable to type a sentence into a search engine because the mouse moves elsewhere. I cannot goto top right hand corner to access my tiled screen. In fact l can't do very much at all. If l take the mouse from the USB port and then replace it all seems well for about 10secs.
I have tried to carry our a system restore about 4 times now but each time it fails.
Any help would be most welcome .
