try going into your device manager and updating the drivers. Right click my
computer, properties, hardware, device manager. You will no doubt see a RED
X, or an ! or ?. This means there is a problem with this device. Click the
+ beside the device then right click on the device, properties, and enter the
driver tab. There is an option in there to update driver. If it will not
update, You need to contact your OEM and get a drivers and utilities cd sent
to you.
hope ths helps.
