Best way to figure out if you have a wireless card or not is to read the box you get your PC in, or, failing that, go into your control panel and look for “Network Connections”, and you should see things like “Local Area Connection”, etc.

If you see something that looks like “wireless network” or “wireless” anything, then chances are you have a wireless card in your computer.

If you see nothing of the sort where you see Local Area Connection, than you most likely do not have a wireless card, and you need to buy one if you wish to have wireless Internet to your PC.

Newegg sells wireless NICs (network Interface Cards) for relatively cheap, I picked one up for my desktop awhile back, pretty useful as it decreases one of the cables I have plugged into the back of my PC. I hope I answered your question Log in to see images!
