I have a Dell laptop (which are apparently notorious for this problem) and recently the mouse has had a mind of its own and has started moving by itself. Occasionally it will drift to the bottom or top corner of the screen and stay there and its really hard to pull it back (the computer is touchpad). I have found that if I shut down my computer and start it up again the mouse is often back to normal. I have tried all these things to fixed it;
1. buying a wireless mouse which gets it out the corner of the screen but it soon drifts back.
2. cleaning the touchpad
3. Running anti-virus software
4. Turning off enhanced precision on the mouse
5. System restore
It still does it and is driving me insane. Please could someone tell me how to fix this, I need it working properly for my exams
