Those install package numbers can be somewhat deceiving and are different than the installed file version numbers.
(For example that package number you give is a 64-bit driver package with ".64" preceding the build number. The 32 bit packages do not have this ".64" in them.)
126.96.36.19959" ? The "19" seems a bit high for that old 2nd generation graphics.
Some users have found success in reinstalling the driver as all settings get reset to factory defaults.
You can first try to install over the top of the other install. If that does not work then uninstall the driver until WIndows lists your adaptor as something generic like "Standard VGA Adapter" then manually point the update driver to the downloaded install package. (If you don't know how there should be help pages on Microsoft KnowledgeBase, or hire a local IT service.)
