Hey guys, I haven't played Starcraft 2 in a while and i recently installed it for the first time on the new computer. When i boot it up the screen constantly flickers and never stops I've tried playing an actually game and still no luck. I have an Asus P8Z77-v Deluxe with an i7-3770k (which is watercooled and overclocked mildly to 4.0ghz) as well as two 7970's in crossfire. MY operating system and the game is off of dual Vertex 4's in raid 0. My monitor is a samsung SyncMaster SA550. Any help would be greatly appreciated thanks!
