The cursor of my toshiba satellite has gone out of control. It keeps on jumping uncontrollable when i attempt to use the touch pad. I can only use the mouse. Please help

The Touchpad is the cause. Although some work fine for years others jump the the pointer every time you type (or sneeze). You can turn the touchpad off if you have a mouse for the laptop. Otherwise, you might need to exchange/purchase another model laptop.

You can try reinstalling the driver. I'm not sure how old your computer is or how much use it's had, it could be that the touch pad is worn out and needs to be replaced. You could try using a plug in mouse or track ball. Track balls work better with a laptop and are more like using a touch pad.

You can change the way the cursor functions. Here is how. From the "Start Menu", select Control Panel in the (right pane), next select Hardware and Sound, select, the "Mouse". In the Mouse, "Properties" (window) change mouse functions. I hope this Fix it

go on control panel and click on mouse and and look mouse crossing settin and set crosser speed.

Try to reinstall you OS it might have corupted file or virus

Ive seen this problem a few times, the problem is that your accidently or inadvertently touching the touch pad as you type. To fix this just disable the touchpad when your typing or put a piece of paper over it. To disable the touchpad it varies on different models but can normaly be done with a button near it, a FN and F1-8 key combo or through the touchpad driver on the task bar. Consult your manual for information on how to disable this.

It's probably a bad contact in your keyboard.
Best think to do is take it out for cleaning.
the service manual should be that one :

you can try to shake it (to if something broken in there), vacuum it (be carefully),
If nothing better think replacement..

hmm quite interesting
has your laptop suffered some damage
i recomend you try to disassemble your laptop and check the connector for the touchpad.
dont know how try this site:http://repair4laptop.org/disassembly_acer.html

Order a restore disk from Toshiba. Windows is gone.

leave it close to a warm oven..just kidding..

that happens for a variety of reasons..go to control panel, and mouse..and check the settings for the speed and other issues of that cursor setting..
