Its windows 98 with a 1.25MHz processor. The graphics card is a 64 MB NVIDIA. Ive just re formatted to get rid of lots of junk/spyware etc.
When reloading the operating system it didn't ask for the video card cd. On the device manager, under Display adapters, it says Standard PCI Graphics Adapter (VGA), however, the card I put in plugs into the AGP port.
