I doubt you guys will be able to answer this, as I don't know how to fix it and nor does the computer forum which I post on regularly and we know a lot about hardware.
Anyways here we go.
I have this stuttering problem. Basically my games (only noticeable in SOME fps games.) stutter. It's not a FPS problem, my fps is usually 80 or so, but it's just like choppyness. This also happens with sound in game. Another problem is that when I'm listening to music and when I sometimes type the music slightly skips.
I've tried everything I think, from reinstalling Windows, to running memory tests to playing around with cpu settings.
I am 95% sure it's my CPU though, which is why I am planning to sell mine and buy a new one (same price though).
