Thats cool about the swap file, I suppose you free'd up a big chunk of resources.. You may also want to look into the amout of space being used for system restore. If it's excessive, I should know a good way to reduce that and make a new smaller snapshot/restore point in a few minutes.

I suppose you will be stuck in that loop if nvidia drivers aren't getting installed onto the drive durring the nvidia setup application if it doesn't see an Nvidia card.... So you won't have any luck with the second link on manually install the driver unless you know what brand/model card you have.. If you have an antistatic wrist strap you can remove the video card, wipe the dust off "GENTLY" with your bare fingers around area's of the circuit board that don't have any components soldered or pins sticking up. These are the places most likely to have the sticker and or silk screen ID tags that should list either the brand, model number, or part number.
