In case this helps anyone, I have an Acer Aspire 5 laptop, 4 months old with a Synaptics touchpad.
A few days ago, the cursor started to overshoot by a few mm (enough to miss the target) when I moved it to the left or upwards.
'Overshoot', meaning the cursor continued to move after my finger stopped.
It seemed like a hardware problem, because the drift was only in some directions. I couldn't find an answer online but deleting the driver (a Microsoft driver dated 21/6/2006) then rebooting did the trick.
The driver reinstalled itself, and the touchpad worked perfectly.
To delete the driver:
Windows key / type 'device m' / select 'device manger' / select Human Interface Devices / right click HID-compliant touch pad / uninstall device
The touchpad will now not work.
Reboot, and the driver (the same one) should reinstall.
