User's Compaq laptop's cursor keeps jumping around screen

A User's Compaq laptop's cursor keeps jumping around screen while the user is typing.

The user uses the mouse track pad that is built into her laptop screen to navigate around her laptop screen.

This happens even though the option to automatically move the pointer to the default point in a dialog box is disabled.

Also the mouse pointer speed is set at the default setting in the very middle.

I have already updated the user's BIOS to the latest levels.

Also I have loaded all of the Windows 7 Home Premium updates.

What else can be done to fix this issue?

How exactly do I "disable the mouse pad touch to click?"
viki2000Commented:
TRy to connect a USB mouse and see if is doing the same.
If not than is clear a problem of touchpad.
Next I would try to identify if is software (OS, settings) or hardware.
I would use a "Live CD" or USB stick, where you can boot in a system directly without install from CD, DVD, USB stick.
If is doing the same then is a hardware problem.
If not then is settings in your current OS.

you are sure there is no malware?
you can always run an AV scan - or MBAM : http://www.malwarebytes.org/mbam.php

Is the user sure she isn't resting or touching the pad while she is typing?  Some use this utility called TouchFreeze http://code.google.com/p/touchfreeze/downloads/list to disable the mouse while typing.

Open Control Pannel and search for mouse.  

click on change mouse settings.

under the tapping tab, make sure tapping is not checked.  

Also, there is an option to select tap off when typing if you want, but it does not seem to work for me.  

I guess I have gorilla fingers, because the pointer bounces all over the screen when I type if I do not turn off tapping.  I just have to use the touch pad buttons.

Have you checked to see if there are any liquid or visible signs under the keyboard or if the keyboard itself can be taken out?
Sometimes the track pad unit itself is loose, or liquid ie. cleaner etc can be used to "clean" the trackpad, though it can seep through underneath.
I'd check and see if you can look in the bios for any track pad options, also have a look for the service manual and see how easy it is to pop out the keyboard unit and inspect around the track pad.

I'm not saying anyone has intentionally spilt anything, though sometimes it can happen.
Also have a good look around the side of the laptop chassis, you might check for any cracks or plastic case coming apart, might indicate if it has been dropped.

So far none of these suggestions listed above have fixed the problem.

What else can I do to help fix these issues?
rtayIT DirectorCommented:
have you tried adding a usb keyboard just to see if it has this issue when one is attached?
viki2000Commented:
If you tried everything what was suggested you should know by now if is a hardware or a software problem. As I suggested above.
So, what is it software (OS) or hardware?

That is the first step. After that we can go further.

test with an external keyboard, and mouse

Resolved this issue by using Driver Genius to find and install the right updated driver.

The driver that it found and installed was one that I didn't see when I went to HP's website and typed in the exact model number of this laptop.
