What's the video card on that machine (and if possible, the date on the driver for it)?.
What I'm getting at is that on certain vendor's PC's (laptops especially), there's often newer OEM drivers for video adapters than the vendor-supplied ones. But vendor-provided updating software won't install them.
I recently had to remove the vendor's video driver (at the vendor's suggestion) in order for the vendor-provided update software to successfully install the latest drivers it wanted me to install!
As a result, I now have video drivers that are a couple of years newer than the ones my update software was telling me were the very latest only days before.
In other words ... don't always take your computer's word for it that there's no newer drivers for your hardware.
