1. No, my entire system doesn't freeze in any way. I only say
"Freeze" because that's how it looks when I'm playing Pinball, the way the bars don't move, but then flips up when the balls already gone down. I can mostly see this problem in games like Stepmania and Pinball. It also does it in the online game Flash Flash Revolution (which is Stepmania but online).
2. Yes, those two games are the games that I find easiest to see the problem, if I understood your question correct.
3. Like I said above,
www.flashflashrevolution.com shows the problem like Stepmania but the notes are a little easier to hit making it a tiny bit more harder to see.
4. It's random, meaning it will happan at any time. It doesn't really show much when typing, only when I'm looking really close to the monitor and when it stops typing for half a second and then goes quickly to make up for the stop time. Or to put it simply - constantly pressing "Num Lock" and looking at the light going on and off and testing the accuracy.
5. Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters - - That's it, isn't it?

Edit:
Here's another way of putting it for Pinball: At a random time when I press the key to make the flipper shoot the ball up, it delays. And then it flips when the ball has already gone down
