If your mouse is clean and you don't have a mouse problem, you might have a sofrware called VNC installed on ur computer. what VNC does is let's others to get on your desktop, when someone gets on your desktop your curson stucks on the screen.  you might have this installed by someone on your computer to check you out.

It's a ghost.\n\nI kid.\n\nYou could just be getting interference from something around it. My wireless mouse will do that from time to time too.

If you are talking about a laptop just putting in an external mouse should do it if not go to the control panel under system/hardware/device manager.

You are in deep and so am I.  The cursor moving on its own thing happens to me all the time.  It freaks me every time it happens, and I swear I can feel a presence.  \n\nOnce when it was moving on its own I put my hand on top of the mouse and I thought I felt a cold hand suddenly on top of mine.

What it sounds like you have done, when it only goes to half of screen is reall just expanded it not moved it. What you need to do is, using your mouse and the left button, click on the task bar in a space where nothing is and keeping the left button down move your mouse to the area, top, bottom, left or right  you want the task bar to be..

Call Ghost Busters!  Seriously though, that happened to me when I was using a hard mouse pad.  Try using a softer one.  It could be that when you are typing that simple action is causing the mouse to move the slightest bit if the pad is a hard one or you are not using a mouse pad at all.

computer freezes or the mouse just doesn't move the pointer?\n\nIf you have a ball type mouse you can take out the ball and clean the wheels it rolls on.

Could be a dodgy mouse or keyboard.  Also try looking for sticky keys.\nIf it is a new computer then send it back and get it repaired for free.

Usually there is an adjustment for the driver that operates it. Check your Windows Control Panel to see if there is anything there referencing a mouse or pointing device.

IBM invented these eraser head style mice many years ago.  You might reinstall the driver and that might fix the problem.  You might try to change the bios mouse settings.  When the computer boots up press ESC to access the bios. \n\nDoes it do this if you are using an auxiliary mouse (PS/2 or USB)--in other words does it happen if you keep your hand and fingers away from the tracking devices-and is the area free of static electricity?

Yes, if it's an optical mouse, this is a fairly common occurrence (depending on what kind of surface the mouse is on). Sometimes the camera gets stuck in a sort of loop that makes the mouse think it's still moving when it's not. This happens to me sometimes. If it really bothers you, try getting a mousepad designed for optical mice.

I don't really know but you might have "Scroll Lock" on and then you can't scroll down with your mouse or keyboard
