I purchased Windows 7 to upgrade my OptiPlex GX260 system from Windows XP. The problem I am having is with drivers and I am unable to change my monitor resolution and I am unable to download drivers from the internet directly. Any answers?
In windows 7, download the latest graphics driver for your computer which appears to be windows xp only, and run it in compatibility mode as windows xp and see if that works. You can also try several different things listed here.
