Sounds like you've done all the basic stuff (uninstall/re-install, update all drivers). The resolution you run your desktop should not impact the game (the game will force 1024x768).

Perhaps wait for patch 1.2? Hopefully when they fix the multiplayer problems for moddir perhaps they can get more of the multiplayer code to work a bit better.

I'd highly suggest you run scumware and virus scans to get your machine as clean as possible.
