Display glitches up when I try to screenshot in Maple.

After talking to a friend, apparently I'm using a really shitty 64mb Nvidia card that's worth no more than five bucks. I've got no idea how to replace a graphics card if I were to buy a new one. My drivers are all up to date, though..

The thing about graphics cards is that you can only use them if your motherboard supports it. If your motherboard can support it, then installing a graphics card if very easy to do. Just open up your computer and find the slot which looks like it's going to fit. Then just shove it in.

Since you're using a 64MB graphics card, I'm assuming your have a very old computer, which means the motherboard isn't going to be compatible with the Graphics Cards nowadays. I suggest just spending about $200-$300 on a new computer. It doesn't need to be a high end computer either. Just buy one that doesn't have integrated graphics and you'll be fine.
