Can a lack of power when running demanding programs like games cause just that program to shut down? Whenever I run a demanding game like WIC or Empire Total War after a random amount of time it stops working and closes. But it takes less time when I have the setting higher. And it takes even less time when I'm either logged on to steam or playing online. Is it the Power Supply. What does the Internet being on have to do with it. WIC doesn't close when i'm not logged on. It's really annoying i can't just sit and play a game they always close. What is happening?
