Shutdown of games can be caused by a few things :
- Weak Power Supply
- Overheating
- [RARE] Device Drivers out of date.
What kind on power supply you have (Min. Advised W. : 420W )
-
Install a program to monitor your current Computer temperature. Speedfan might do good.
When your playing, Go out of game and check on the temperatures of mainly the HDD, CPU or RAM if provided.
If a yellow 'flame' gets displayed before the temperature, then you probably have a overheating problem.
You can also try to get one of the sidecovers off the case so it gets more fresh air.
If the device drivers are out of date, lookup the model of your graphics card and go to one of the website's below (depending on what card you have )
