Rendering in H.264 causes computer to crash.

When I try to render a recent video in the H.264 format my computer crashes partially through the process. I do not get a BSOD, the screen cuts to black and does not power down. I have successfully rendered in AVI and quicktime. I have searched the forums and other sites, but I haven't found any solutions.

• I am using Premiere Pro CC 2017
• All updates have been installed
• I am using Windows 10
• The source footage is MP4 recorded with shadowplay by Nvidia
• When the problem occurred I was just allowing the video to render
• Rendering in H.264 has worked before, but I was using a different CPU
• At first I was running chrome during the rendering, but during repeat attempts I only ran Premiere
• I do not have any other third-party effects or codecs installed
• Hardware
  • CPU- AMD Ryzen 7 1800X
  • Cooler- Corsiar H110i liquid cooler
  • RAM- Corsair Vengeance DDR4 32 GB 2800 MHz
  • GPU- Asus strix GTX 980 x2
  • HDD- 2TB WD Blue
• I have tried Mercury Playback Engine GPU Acceleration
• I have also tried Mercury Playback Engine Software Only
• It does not happen when looking at the preview, only when rendering the video

Thank you in advance for any help you can provide
