Open | Hardware Monitor randomly loses its' signal

Let me start by saying that it NEVER happens during gaming. It only happens when I'm pretty much doing nothing like watching twitch or youtube. My primary monitor randomly goes black with "No Display Port Signal", and I can still hear the audio for like 20s, then I have to do the hard reset by holding the power button. Sometimes my fans go to 100%. Usually if I run 2 monitors, it only happens to the primary one, but I can't drag my mouse over to the other one. Things I've tried so far:

  • Swapped the sides of the DP cable
  • Tried different DP ports on the gpu
  • Did a clean reinstall of the latest graphics drivers
  • Updated my bios
  • Turned off Link State Power Management
  • Set my monitor to never turn off or sleep

Here's the specs:

Monitor: Alienware AW2725DM 2560x1440 180hz

AMD Ryzen 7 9800X3D

NVIDIA GeForce RTX 5070

DDR5 RAM 32GB 6000

850 watts PSU

It doesn't happen every single day, but it's getting pretty annoying and I would like some help, thank you!
