Keyboard Registers Twice Before Starting The Repeat Cycle

I have the keyboard settings set to minimum delay before repeating, and maximum repeat rate. My problem is, no matter these settings, when I press and hold a key, it registers twice before starting the repeat cycle. For example:

I press and hold "A."
Computer registers: A...A...AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.

Obviously for a game that requires keys to be held down, this is a major problem. I also know for a fact that this happens with every key, and that the problem is with the computer, not the keyboard (I have tried many different ones). I don't know if my driver was installed twice or something, that seems to be common, but I haven't been able to find any solution to this problem.
