Video Mode Not Supported

-autoconfig does not work. -window also does not. None of these commands work, for ANY program.

Really? Hm. As an example, I have a link to Half-Life dev mode in my quicklaunch.
When I right-click it and choose Properties, under 'Target' I have "C:\Sierra\Half-Life\hl.exe -console -dev" (sans quotes).

When you try to use these commands, are you sure you're adding them to 'Target' not 'Start In' or whatever?
If command-line options absolutely won't work, then something is wrong... try running a virus check or whatever, or post in a dedicated troubleshooting forum, 'cause it's important to be able to use commandline options, on any system.

Couldn't be a virus. Wasn't working before i even got connected to the internet...
I think the only one that worked was dev... for Halo CE...
Maybe it's just game-specific?
