Hi, I have a serious problem. Here is my pc specs CPU = i7 2600k 3.4 gHz GPU = MSI lightning 6970 2gb RAM = 8gb I played battlefield 3 a couple of hours in ultra ultra mode with absolutely no lag and no glitch.. nothing ... perfect !!! .... But suddenly, some graphics glitched. Things around me started to change colors like blue, red, green, white and black if you know what i mean ... something like a cyber graphic glitch and its annoying.. Can you help me to solve this problem please .. Am very sorry for my bad english.
