So i've searched far and deep for a solution to this problem but i have come up with no solution at all. My computer ran Unreal Engine games fine before i did my first reformat on the computer. I am now on my second reformat and i don't have any Unreal based games able to launch. well to be more specfic they launch to the splash screen then to a Blue screen with the error page_fault_in_nonpaged_area. I know it's only Unreal games because i tried several other games such as Hawken, all Source games, Call of duty Black ops 2, Arma 2, Planetside 2, and they seem to work just fine without any problems. I am just totally stumpped now. so heres what i have done so far.
Tried with no solution:
Roll back Graphic drivers
Memtest all my sticks. they came out with no errors. i even did one stick at a time.
Messed with the DEP
Disabled my Anti-virus
since this is the second reformat and after the first this started happening i don't think reformating will help again.
