My PC froze up hard four times while I was playing. Turns out my CPU was overheating. I got a program to check the temperature and I cleared out some dust, but the game still ran pretty hot. I had to play with the case open. I haven't had this problem with any other games, but I've mostly been playing strategy games lately and those rely more on ram for performance rather than the CPU so this is the first game in a while to need a lot of real time processing power. This seems like a hardware problem on my end, but is there any way a game could cause overheating without there being a hardware problem? My usual computer fixing place closed down so I don't want to have to find some place to take it to unless I have to.
