Laptop blues...

I've had this piece of **** since last xmas. It's caused me nothing but headaches since. I've had to get the mother-board replaced twice..
Regardless, my Mac is in Geek hospital at the moment, she caught a virus. Didn't know that could happen...
So, now I'm using this garbage until my baby get's fixed. Anywho..
My question is - I've had tried every trick I can find on how to disable the touchpad. I disable it and a few hours later, it's baaaaack.
I've tried uninstalling it too. After a whole bunch of restarts, it's still here. It's screwing up my writing life!!!
Does anyone know how to kibosh the damn thing? For good, permanently? I use a mouse, so no worries.
It's a HP and if I touch the freakin' touchpad, I lose everything I've written or the font grows or shrinks exponentially, or unwanted pages appear or it turn my keypad into spanish. I'm getting close to tossing this thing out the window. Please, if you have any ideas aside from stomping on it, I'd appreciate your help.
Thanks.
