Asus M6N bios problem? Please help!

Hey everyone I've recently aquired a "busted" Asus m6n laptop with an interesting problem. Whenever I turn on the machine, it acts as if I'm constantly moving the mouse cursor around until I hit down on the arrow keys. It works fine for a few minutes but eventually, when I'm on the internet for example, it constantly refreshes the pages and makes selections on its own. I've tried disabling the touchpad in the bios, but it didn't work, and the problem occurs even in the bios sometimes with the cursor flying around everywhere.

So my latest theory is that its the bios. It was at 0208 in the beginning, with the cpu running at 500mhz, so I flashed it with 0214 (I believe, its the only m6n bios they had available at the asus site) which runs the cpu at 1500mhz, and the crazy random selections are going really, really fast now. Maybe I'm just overclocking it, but I'm hoping that there's a bios out there that could fix the problem.

I'm kind of a noob at this kind of stuff, so maybe I'm wrong about the bios, but does anyone have a suggestion on what I should do?

 

I think it's the touchpad itself has problem and need to replace, I do remember seen that in the past.

 

can happen if liquid was spille don the touchpad
