My computer runs cracked version on windows 10 pro which at the time I built this I didn't have money for the operating system at the time , the issue is that I dont know if it's the os breaking or my hardware but in games it will stutter or just straight up crash but it usually happens in multiplayer games, I can run games like borderlands 3 fine but games games like modern warfare. Any input would be helpful.
My hardware is as follows,
Ryzen 7 2700x
B350-F asus motherboard
Rtx 2080
16gb Corsair vengeance pro 3200mhz ram
650w psu
