PC Keeps Restarting/Freezing While Playing High End Games

[tunnelsnakeirish]

Hello, all! I have an AMD FX 8350 and a GTX 970 G1 Gaming edition along with 16GB of ram, my PSU is 600 +50 I am pretty sure. Now when I play games like Garrys mod, tabletop simulator or something small it will not crash but. When I play The Divison or Overwatch or Arma three it crashes after about an hour or two of playing but sometimes a whole lot shorter than that. Sometimes it freezes and I have to shut it down manually and then other times it fully restarts my PC and just reboots to my Desktop screen. Any idea on why it is doing this?

Hi,

There could be some bug with the graphics card driver. Please do try these troubleshooting steps.
- Go to Device Manager and uninstall the Nvidia graphics driver.
- Next is to open Programs and Features then uninstall anything related to Nvidia.
- Once completely uninstalled, download and install the latest driver.
- Here's the link: NVIDIA: http://www.nvidia.com/Download/index.aspx
- Reboot your PC once the latest driver has been installed.
- After the reboot do observe it again and see if the same problem will persist or not.
