There you can enter the exact model and download the driver.

Not without some serious modification. I wouldn't recommend undertaking that project unless you either have some previous experience modifying electronics, or you want to risk breaking the device.

Here's a touchscreen monitor that you can purchase: http://www.newegg.com/Product/Product.aspx?Item=N82E16824176142

Here's some information about modding a touchscreen overlay onto an LCD. http://beta.ivc.no/wiki/index.php/Eee_PC_Internal_Upgrades#Touch_screen This is specifically for an Eee PC, but the method would apply to a regular LCD. As you can see, it is quite a lot of work.

I hope this has been helpful.

Use the 7.13 build on the following site. it will work with this model.

I have had the same problem with my dell touchscreen. This problem seems to happen with the newer driver software. I reinstalled the older 5.64 driver and actively touch the screen at start-up when I enter the windows password and it seems to work fine.
