Well three days ago I bought a wireless keyboard and mouse bundle and yesterday my computer started acting up. Internet pages would scroll to the bottom of the page and when I tried to scroll up it would go straight back down. Also, on Start menu, it would scroll through all of the options without stopping. It was as if the down key was being HELD, so I obviously thought it was a problem with the keyboard or mouse. So I reset the keyboard and mouse connections, no change. I then unplugged the USB receiver, no change. Which made me think that it is something to do with the computer and not the keyboard or mouse. Thanks for reading and if you know anything it would be a huge help and I'd be very grateful Have you tries a different mouse and keyboard? It sounds like it is the mouse or keyboard at fault, maybe an internal fault in one of them, so that resetting them will have no affect.Thanks I'll try that and see if it works OK, well let us know if it resolves the ISSUE Thanks a lot for your help but I realised that it was because I hadn't unplugged the LAST keyboards receiver, and a key must have been pressed on it He he sorry for the trouble
