How to troubleshoot? Monitors go blank

Hello,

My Aurora R8 randomly turns off all 3 monitors at once.  Not sure how to troubleshoot without a functional display.  Tips?

When the issue happens:

• Only when I'm using it for work purposes:
• RDP, MS Teams, MS Edge occasionally
• I first I thought it was my Logitech Brio webcam.. but issue happened without it being used too
• All monitors go blank, power off
• No change to the PC sound and appearance, fans stay running, LEDs stay lit
• Unplug/plug all devices, nothing helps
• Force power off / on and it goes back to normal (abnormal shutdown message of course)

When the issue happens AND I'm in a MS Teams meeting:

• I will start to notice some lag or complete freezing in other peoples video streams
• The 3 displays turn off, but the audio for the meeting still works
• This gives me time to join the meeting on my phone, reboot and rejoin quickly on my PC

The common factor is MS Teams and/or a headset so far but I have no evidence that is causing the issue.

I have:

• Stock R8 PC, except for the Logitech Brio external webcam and headset
• Windows 10 Pro - up to date firmware and OS
• NVIDIA GeForce GTX1080 - up to date via alienware
• Alienware software to keep PC up to date
  
  
• Played games without issues for hours on end
• Run this stress test tool "Heaven & Valley Benchmarks" at max settings for about 30 minutes, no issues 

My Thoughts:

• Cant be GPU temp issue
  stress test showed GPU was being throttled by max temp for XX minutes.  It never runs hot during "work" sessions
• Dont think its a power supply issue - factory Dell equipment 
• Cant be display issue
• I dont see issues or errors in the Windows event log (app/system)

What else can I do to try to finger this out?  I can't make the issue happen on demand.
