Need Help, Somethings Wrong!

[Shreky]

So a friend of mine has been experiencing some weird problems with his PC, in battlefield 4 his gun wont appear, or when it does (eventually) and some people will kill him but they are physically not visible. In a star wars game he describes that if he goes to a market place AI he cant load things, it would take a good 2 minutes to load the screen, and in that time nothing around renders and all the textures and everything wont render in, but the walls etc are still there, hes running two 560's in sli and hes got 8 gb ram with i5 2500k. Im sorry if im not extremely descriptive this is the info hes giving me and i wanna help him. Here are some screen caps of him in the Star wars game, of his gpu mem(sorry if this is useless).

start with trying to boot into safe mode and remove any of the older nvidia drivers and microsoft direx drivers. then reboot and reinstall nvidia and microsoft driect-x drivers. make sure there not damaged. if the error still there turn the pc off and try the games with one gpu if it fine swap gpu and see if the error not there. use gpu-z make sure both cards are working in sli mode and not just one. if the error in sli mode have him clean the drivers out again and try an older driver. it could be a driver issue between older hardware and the game drivers.

Did any of this start after a recent Windows update for driver update? What are CPU/GPU temps like in his system? Also, I'd try a different version of Geforce drivers than what's currently installed just to narrow that out as well. Besides textures not loading, is whats on the screen that should be there look correct, or is there visual artifacts as well? I'd look into these for starters.
