Ok so I was using my Asus computer day to day with an Advent remote keyboard with scroll pad and one morning it just decided to not work properly . I have to press and hold every key for two seconds for it to type. Reinstalled windows, still the same. Tested keyboard on another computer and works fine. during re-installation of windows 8 it worked fine in the bios but as soon as windows loaded it was back as before......
