Just to be clear, it is this mouseover effect that I'm talking about and I hate:
Maybe it's unrelated, but whenever this effect is...well, in effect...Resource Monitor looks fine. When it isn't, Resource Monitor is 100% transparent. I thought disabling visual effects would get rid of this mouseover behavior, but, at least in Areo themes and the Windows 7 Basic theme, it doesn't.
There are no updates available for the video driver. Maybe I should reinstall the existing driver? Maybe I'll be getting a GPU sooner rather than later.
EDIT: I never really solved the issue, but concluded that it must have had something to do with setting up User Data on a separate drive from the OS (I may have included Program Data. I can't remember for sure now). Anyway, I installed Windows 8 in the same configuration via relocate.xml and it is no longer an issue so I thought I should mark this thread as solved.
