Flickering graphics on GTX 580

[zniff]

i have a Gainward Geforce GTX 580 phantom 3000mb, and something is weird with the graphic ingame
it flickers when im a bit far into the game

games i play it happens in is starcraft 2 and dota 2

Does this happen in both games or just one of them? Did you try updating your graphics card drivers?

i have tried uninstalling and reinstalling the drivers. and noticed also that it does not like me pressing the windows button when im in dota 2, when i get it back up the same thing happens only earlier than it would by itself. and yes in both games it happens. it looks like pointy things starting from one end of the screen and stretch over half way across the screen.
