Intel is offering a different version of the graphics drivers. Have you tried updating to the latest?
This is version 220.127.116.111 and you can download it here:
thanks for the information. I'm gonna forego any more updates for now since things seem to be
working on my clients' computers.
Someone from Intel needs to let Microsoft know that they're clobbering a bunch of laptops with
an Intel diver that doesn't work and get them to stop it.
