This has happened twice. Just changed around some BIOS settings to improve CPU performance while streaming. I was seeing CPU spikes/drops when streaming, so I messed with some BIOS settings, most notably turning off the Automatic OC settings.

I am running HWMonitor...temps don't go over 85 C, but I don't know what is normal. I don't notice strange processes happening before the "crash", if we can call it that. I am running XCOM and streaming to Twitch using OBS.

When it crashes, I lose signal to both my monitors...one on HDMI and one on DVI. I also lose audio and power to my keyboard, mic, and webcam. The PC power light is still on, and the fans are still running.

Check that your graphics card is fully seated, you might even take it out and put it back in. Are the latest and greatest drivers installed for your card?

I will try reseating it and will let you know. Just uninstalled old drivers and installed the newest version. I feel like its not the GPU though because that wouldn't cause me to lose power to all my peripherals and lose audio
