I have always encountered crashing issues in Modern Warfare. I think I've watched almost every youtube video that is supposed to "fix" it and I still have the issue. I've always thought it was my CPU since it was poor compared to my GPU. But I saw a thread here and someone mentioned that any PSU less than 550w could cause crashing issues. My specs are:
CPU: AMD Ryzen 3 2200G
RAM: Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3000
GPU: MSI Radeon RX 580 8 GB ARMOR OC
PSU: EVGA BR 500 W 80+ Bronze Certified ATX
