Issue with Synaptics Touchpad driver on ASUS Laptop

    Question

  • Hi I have an ASUS N81vg laptop which has a Synaptics touchpad built in, recently I had a blue screen and the touchpad stopped working correctly.  After a few system restores I got the machine up and had to reinstall the driver for the touchpad (from the ASUS site) and rebooted, the touchpad worked for 5-10 seconds on reboot then Windows installed the Microsoft PS2 mouse driver and the touchpad stopped working.  Additionally my Nvidia GT120m started having an issue at the same time, so i updated the video drivers.  It seems now the only way to get the video card to work correctly is to disable the Synaptics touchpad.  The machine is now running with an external usb mouse but the touchpad is disabled.

    I ran msinfo32 and the Video card and touchpad are on different IRQ ports and do not seem to share the same resources, so I think it might be a driver conflict.  Can you suggest a way of confirming this and what the reccomended course of action is.  I have tried system restores but these got the machine functioning but did not resolve this issue.

    Regards

    Simon
