So my computer seems to be having trouble pushing out a display, yet everything turns on.. Including the GPUs lights & fan. I’ve done multiple tests:
  • Switched GPUs, no change.
  • Ensured all cables are plugged in, and they’re all perfectly snug.
  • Ram is tight
  • Tested on different monitor
  • Tested monitor itself (PS4 into monitor), worked
  • Changed PCIE slots
  • Changed HDMI cables, and even bought a DisplayPort

After all of this, nothing changed. Any ideas on where I can go from here?

So I reset the CMOS and that ended up fixing it.. However now I'm concerned on what actually caused it to happen. All I did was unplug the back I/O to move it, and when I plugged it all back in that happened.

Specs in case it can help answer that, if not thanks guys:
Ryzen 5 2600 OC 3.7GHz 1.325V
2x8GB 3200MHz Corsair Vengeance
RTX 2070 Strix OC
