It's onboard video. It's attached to the motherboard and not a card. Integrated I think is the word used.
It was a built machine but not by Dell or HP. A guy I know builds them up from scratch all custom-like.
The "system" is, again, custom. The motherboard would be the only thing affecting this. That or the driver. I run Windows XP Professional on it.
Wada ya think?
