Windows 7 - Strange mouse/input behavior

I have a HP Presario laptop.When I get very close to where I want to go (with a Logtec mouse or with the inbuilt mousepad ) the cursor will suddenly shoot away,usually to the bottom left of the screen ?
Example: I am about to close a window.So as I go twords the top right of the screen,when I get a few centremeters away from the cross the cursor will suddenly shoot of to the bottom left of the screen.This will happen around 3-4 times out of every 10 times ?
It cant be a virus or malware or anything like that as my laptop is not connected to the internet.

Any help with this strange problem will be much appreciated.

I would suggest you connect to the internet and download all the latest updates from MS and then check and make sure you have the latest drivers for your mouse pad on laptop and for logitech mouse.

I will try that,but you would think that when you buy a new PC everything should work right from the start.I realise that you may have to update your drivers but the ones that came with the PC should work, especially as the PC is not connected to the net.
