We can't tell you what video chip your computer uses. If you don't have any documentation, you may have to look inside the PC. It's either on a videocard (the one your monitor cable connects to) or a chip integrated on the motherboard. Most common are nVidia and Ati chips, but there are half a dozen others as well.
It would be best if you could use a rewritable disc (as not to waste a blank dvd for just a couple megabytes). A USB-memory stick could be another option (and there's more). If you use Nero, burn it as a "Data-disc".
