Hello everybody... I'm just new here, sorry for my english. I need some help please. I just bought a new PC with the next configuration: ASUS Crosshair IV Formula Phenom II X6 Patriot "G Series" Sector 5 8gb (2x4gb dual channel) ATI Sapphire HD 6850 OCZ Vertex II 60gb OCZ GameXtreme 700w Corsair H70 Cooling System I'm having troubles with it. I don't know if it is video or ram. I think is video but concerning to PSU. if some one has seen this before and can tell me what it is i would apreciate it. The best example i have is when i open chrome and run the new addon of angrybirds automaticly video crashes, blue or color vertical lines appear then screen goes black and PC frezze. Is weird becouse i can play Splinter Cell Conviction at AAx16 all setting at high for about an hour and system does not crash, some times it crashed instantly. This is close picture to the monitor of the video artifact.
