Random speed up help needed

Ok,so i am currently playing metroid prime 3(Trilogy version),and in random moments it speeds up on itself as if im holding the TURBO button to speed up which i am not.. and it happens very often btw. So I figured,ok maybe its just the game.So i tried Spryro Enter the dragonfly and SAME thing occurs.I tied several other games with same outcome.I tried using ALL video backends and messed with the framelimiter,all settings with no success.

Specs:
Asus Z87 Deluxe
i5 4670k@4.4
