hey buddy..i had the same problem..n i was fedup ....i couldn't find the solution .....until i did what was
necessary to do .......u could go ahead with all the other solutions found online and if that hasn't worked out this is the final step u need to take ......to get rid of it
what i did:
1) u need to disable the page up and page down key from the keyboard.....(in my case the scroll would go down always so i only disabled the page down button)
2) mind u once u have disabled the particular key ;the key wount work , also u can turn the key back on manually later.....so changes not permanent
