Is the computer a desktop PC or a laptop/notebook?
are the keyboard and mouse both located on the same surface? Maybe you're pounding the keyboard , thus causing the mouse to move slightly. If that's not the cause, you can try replacing the battery in the mouse. If that doesn't fix it, try opening Control Panel/Device manager. In Device manager double-click on Mouse. Click on Driver tab. Click on Update driver. Alternatively, right-click on Mouse (in Device manager) and select Uninstall, yes, ok.
Restart the computer by holding down the Power on/off button for about 6 seconds. Wait 10 seconds then press the Power on/off button again to turn the computer on again. When it boots up it Windows will reinstall your mouse.
If you're using a touchpad go into Touchpad properties (usually located in Mouse in Control Panel). In Touchpad properties window you can adjust the sensitivity of the touchpad. On our Lenovo laptop, for example, the cursor would frequently jump, jitter, or otherwise move around when we were typing. Sometimes it would move slowly around even if we weren't typing. After adjusting the touchpad sensitivity in Touchpad properties window the cursor became much more stable, and it only moved slightly if I was really pounding on the keyboard.

Hello
Most probably because your 'Touch Pad Mouse' is touched by your palm (hand or something) while you are typing. Avoid contact with the mouse touch pad while typing.
Option 2:
If you have a centre moveable mouse on your laptop, start using it and disable the 'Touch pad mouse'
Best of luck!

well..that can happen when the palm of your hand touches the touchpad, as you are typing..happens to me all the time. try it with your hands a bit more over the top fo the laptop..

I frequently have the same thing when using a Dell laptop. The problem MAY be with the touch pad. Without noticing it, my thumb touches the pad and away goes the cursor!
So try this: Open the control panel and go to mouse. Look at the top for Touchpad. There is a setting in there for sensitivity. Reduce the setting so that you need to apply more pressure on the touch pad to move the cursor. Test it a few times to make sure it is still functional before closing the control panel. Then try typing something in a word processor and see if it is any better.
Good luck, and please let me know if this helps.

go into mouse properties and look for a check mark that says something like "disable touchpad while typing" make sure thats chkd off. if not chk the box and problem solved

If you have a laptop with a touchpad just below the spacebar be careful that you are not accidentally hitting the touchpad. I had an identical problem on one of my laptops, and simply switching to using a mouse and turning off the touchpad fixed the problem for me.
