Every single time I open Modern Warfare 2 it automatically restarts my pc, won't even make it past the first loading screen and it shuts down, I can play any other game fine but any Call of Duty, I upgraded my power supply changed to a watercooler and even reset all my drives and this problem still persists, MW2 was working fine before i upgraded my CPU GPU and motherboard, then it started to happen. Anyone who has any fixes or tips please let me know.
