OBS Crashing PC On Startup (Loses Monitor Signal & Restarts)


New Member

When starting OBS my PC crashes and restarts or doesn't show display on both monitors.
  • Can take a few seconds of the application fully running to then crash my PC
  • The crash causes both displays to go black in which they have no signal from the PC
  • In some cases once OBS is launched it will drop the signal a few times before losing signal completely
  • In some cases the screen goES off due to no signal and after a few seconds the PC reboots
Issue that could be related:

Have updated Nvidia Broadcast Audio Effects and Video Effects to the latest version.

Steps I have currently taken:
  • Updated the graphics drivers to the latest version
  • Ran OBS in administrator mode
  • Unplugged one monitor and ran OBS
  • Have done a clean wipe of graphics drivers using DDU in safe mode
  • Have restarted the PC and ran OBS
  • Disabled Nvidia Broadcast from running in the background and opened OBS
Hardware Specs:

  • AMD Ryzen 3900x OC 4GHz
  • 64GB DDR4 RAM 3200MHz
  • Windows 11 Pro (v 22H2)
  • Zotac RTX 4090


I have attached all three OBS logs from my last three attempts running the application.

Have uninstalled streamelements and OBS seems to be running perfectly fine for me now. It seems to crash when trying to connect to YouTube for activity feed for some reason.
