computer scrolling by itself

[ShadowBlade]

occasionally, my computer will start scrolling by itself in any program

i.e. i was listening to music in MPC and the volume started going crazy

is the down arrow on your keyboard jammed? or maybe your mouse scrollwheel is going bad

wireless keyboard/mouse?

I ended up formatting my hard drive (needed to anyway)
seems to have gone away

Hi, Wheel is also a switch. Push down on it and you get a round target with arrows pointing in all directions. While that target is on the screen the scrolling will follow your cursor in any direction. Is it possible that you hit it by mistake? Happens to me occasionally. Good Luck, Jim
