Ok so I picked up an older used Dell desktop just to do real basic stuff. (my newer HP got fried beyond repair! The only things that were salvageable was the 360gig HD and the 2 gigs of RAM) The most demanding thing I might do is edit videos for youtube on this old dentist office computer. That being said, I picked up a few used parts to upgrade this old business workhorse. I bought a used Nvidia GeForce FX 5200 video card and a sound blaster sound card (both the older PCI) Both did not have any install disks. They looked fine. (no blown capacitors or bent parts or anything obvious) Do I just plug and play these cards or do I need to configure something to run them properly? My other question is...I cant find the video card anywhere when I tried to look for it on the computer? I tried "my computer" and "control panel". The only thing I saw was that the computer "found new hardware" at initial boot up. Where do I verify its existence?
