I'm looking for some help with SC crashing my PC after about 5-10 minutes of gameplay. I've been getting the blue screen of death showing up with different stop codes for about two weeks now, a few days before 3.4 launched. I used to be able to play for hours without a crash. The codes I'm getting are: System Service Exception Page Fault In Non-paged Area IRQL Not Less or Equal Kernel Security Check Failure APC Index Mismatch I have tried the following to get it to stop happening with no luck: Changed graphic settings to Low, Medium, or High Turned off V-sync Changed between Fullscreen, Windowed Fullscreen, Windowed Reverted back to an older video card driver Took an air-hose to the system to clean it out Reformatted the SDD drive SC is on and did a clean install of the game Restored the system completely Did a memory diagnostic scan and it was clean All of my drivers are up to date and I do not overclock my video card. Here's my setup: Windows 10 Home 64-bit Intel Core i7-4790K 4.00GHz 24 Gb of RAM GeForce GTX 980 Ti Gigabyte G1 Gaming GA-Z97X-Gaming 7 motherboard Any help is appreciated.
