Okay, this is probably going to sound sad to some of you, but I'm trying to find a replacement processor for my computer that's compatible with my motherboard. I don't have a lot of experience with processors, so I'm getting a little confused. My girlfriend's old computer has an AMD Athlon 3200, but it won't work in my computer. I was trying to replace the chip that is currently in my computer, which is an AMD Sempron 3000+. I know hers runs better than mine, even with the same amount of RAM, and my better graphic card. Does anyone have a suggestion? I can't get hers to work, so I can only assume it's incompatible with my motherboard's socket, despite fitting as perfectly as the Sempron does. I don't need something too powerful, and I'd prefer to not spend over a hundred dollars on a new one.
