'Ive had to re-install Windows on my laptop, but because it is a retail copy, rather than the pre-loaded one I need to "install" the touch pad (it works, but there's no adjustment of zones, speed etc.)
The touch pad (usual Synaptics) does;t show up in Device Manager or anywhere else that I can find.
On 7, IF I remember rightly, for sound, then device manager, sound video and games controller. Right click where the yellow warning is and search for drivers on the PC. It should give a clue as to it's name . I got Realtek. If so then look here.
The images should install even on a new hard drive. That's the whole point of taking an image. I agree with not using the restore facility, as you say, you get a lot of crud with it. What does Windows updates show? Have you tried device manager then searching online for drivers? Selecting the ones with the yellow triangle then properties.
morddwyd , here is a site for all drivers for your machine. Its not an Acer site but McAfee shows it's OK. It's up to you to try it out. I think it's alright though. PS, forget the rather large green tab trap :)
