This randomly started happening a few months back and it's driving me insane. I can't figure out how to fix it. I'll be playing a game perfectly fine and then suddenly it'll drop to like 12fps and my cpu usage will spike to like 99% thanks to a process called systeminterupts. When this happens I need to alt f4 or it crashes my whole computer. When I alt f4 the game everything goes back to normal and I can start the game back up again. Please help meeeeeeeeeee~
