I recently went to start up my computer and it ran fine for about 5 minutes and then I got a bluescreen. It said PAGE_FAULT_IN_NONPAGED_AREA with a value of 0x00000050. I haven't changed any of my hardware, the only programs I installed in my last session were War Thunder and the RUSE Demo. I can't boot into startup repair either. Can anyone help me figure this out?
