My computer was acting weird every time I tried to run Call of Duty. The computer gets really slow and the game crashes before starting. It worked better before this. Some where I read that it might be due to cpu heating up. I checked the temperature on my BIOS and it was 50 degree Celsius which I think is too much for it to handle. I think cpu cooler is best way to avoid it. What do you think? Which one should I get?
