Me either, but it doesn't stop me!!!

You should take your computer to a shop to have them check your motherboard. It doesn't really sound like a good idea for you to be poking around in there. There is no shame in not being a strong computer user. Just remember, you aren't a strong computer user YET. You will learn and grow into it and the learning never stops.

Okay, IF you can get the side cover off the computer, look inside along the big circuit board. That is the motherboard, so named because just like a family, everything is supported by the mother. A STANDARD PCI slot will be white and about 3 inches long running perpendicular to the back of the computer. Looking down on the slot, you'll see a "slot" or a "key". That will come in WAY down the road.

A PCI Express slot will be about 1 1/4 inch long.

An AGP (video) slot will be brown.

A lot of this is going to depend on how old your computer is. If it is "pre PCI-E" and "PCI-X" you will have standard PCI slots. That's why I suggest you take it to a shop and let them look.

You can find this stuff Wikipedia but step 1 is being able to see your motherboard, which means taking the door off, and again, not knowing your experience, I don't know how that will go. Just visit Wikipedia and type in PCI SLOT and you will get explanations and pictures of what the cards look like that fit the slots. The "notch" in the card has to line up with the slot, and that determines if it is 3.3v or 5v data bus. And just for another wrench in the works, some cards will work with either 3.3v or 5v.
