I downloaded a driver update for my GTX 970 from NVIDIA on the 14th. Since then I haven't been able to start DayZ nor Arma 3. Instead, it begins t0 load then quits giving me the error message "The exception illegal instruction an attempt was made to execute an illegal instruction. (0xc000001d) occured in the application at location 0x000000006CAEDB41. Click OK to terminate the program" I've tried numerous things to attempt and fix this but my lack of knowledge and success is beginning to depress me. I uninstalled the driver and reinstalled the one I was using before without any success. I uninstalled both games a few times and even uninstalled Steam once. I scanned SFC in the command prompt (I'm not even sure what that means) but that found nothing wrong with my OS. Basically trying anything I read on the matter as it's been 5 or so days and I really want to play with my buddies. I I'm definitely at my wits end so any help will do and I really appreciate it.
