So, I started downloading Grand Theft Auto V and a few minutes later i could hear a very faint rattle. It seems to last a few seconds at a time and is sporadic. It's not obnoxious or anything but i can hear it every now and then. I stop the download and it seems to stop. I made sure that it wasn't plastic pieces or anything hitting the case of the computer. So is this just because of the download or should i be concerned about this?
