PC error shutting off video to monitor. Please help.

[Saiyan]

I tried to install my new 8gb of RAM stick the other day and for some reason through multiple tests I figured out that my new stick is a DOA and my old stick works fine. Tried multiple slots, different arrangements, everything, that's the only thing different I've done with my computer lately. Fast forward to today, just running my old stick of RAM like I have been for years and I startup overwatch and crash mid game... PC and sound are still coming through fine but the video signal to the monitor was shut down with the windows error sound accompanying it. Checked device manager and all my drives/gpu seem to be working right.  Ran malwarebytes just in case but sure enough the scan came back with no threats found. Disconnected my GPU and re connected it and sure enough the same thing is happening and it's random as all hell. 

All PC components are in my signature. 

Used CAM to monitor temps and usage percentages and nothing out of the ordinary is going on there. 

 

Tried recording with OBS and capturing to at least see the error but the file is corrupt after the computer resets. Reinstall Windows?

 

updated GPU drivers and still crashing..
