The touchpad freezes for long periods even after resetting Windows.

Looks like a driver problem but I tried installing a previous version from the HP product page and it doesn't work, it says it can't be installed on this Windows version, whatever that means, so I have to use the last Synaptics driver and it happens totally random and stays frozen for long times. I start touching keys, open the Windows start menu and eventually it will move again but with no know reason.

Any suggestion?
