Hey guys, seems like about a week ago this started happening, every 45 to 2 mins i get a pinwheel for a good 5 seconds then it goes away.... this does this in everything and it lags whatever is open. like if i am watching a movie, the movie stops, then skips ahead 6 seconds... if i am typing it will stop and then show what i typed... this goes for anything... i have no clue what is wrong i repaired permissions, and ran heaps of stuff in onyx... still the problem remains... help?
