Re: Installing an AGP card.
Are you using an exisitng hard drive for that new motherboard and everything else? I would suggest the reformat part too because you're installing a new motherboard to go with that video card.
Do a clean reformat of the drive and plug it in to the case along with your motherboard, video card, etc., etc. Install Windows, driver discs, etc., etc. If you don't want to use the drivers provided by the video card manufacturer (I wouldn't because it's so old), then go online and download the latest forceware for that video card and install. Everything should go very smooth. I'm backing up MoneyMan on that solution. If it's just a video card you're upgrading, then all you need to do is simply install that sucker in he AGP port and install nvidia drivers for it. That's it.
