Yep video card problems. I'd make sure it's not a driver issue, but 
re-installing the driver if one is available (or re-installing the latest combo 
update for your OS) but all of those symptoms point to video issues rather than 
monitor issues. If you can swap in a known-good monitor and cable, that would 
be definitive.
