Need more info here, are you talking about video settings? Hit F8 after the BIOS screen but before Windows starts to load. Select VGA mode. Re-install the video card drivers, should reset it to defaults for it, reboot and you should be OK. And stop playing with video settings if you are not sure what they do.
