My display settings will frequently change itself from the highest resolution
to the lowest resolution without user adjustments. It is often impossible to
reset display settings afterward without a re-boot. Sometimes one user can
reset resolution but another cannot. Sometimes none can.

Not sure if this is a display card issue, OS problem or of it's being
triggered by an internet-based program that may be running in the background.
Even so, the problem often persists even after closing all webpages and
logging off Internet Explorer.

Running Vista Home Premium SP1 with GeForce 6150SE nForce 430 adapter on a
Dell Inspiron 531.

It indicates a corrupt video driver. I would reinstall it.
Go to Start/Run, and type DEVMGMT.MSC , highlight the Video Adapter device,
Action menu, "Uninstall", (do Not put a check in 'delete driver") then
Action menu,"scan for hardware changes", to find the device drivers again
automatically.

Thanks for the response. I followed your instructions and haven't had a
problem since.
