Monitors go black/shutdown while playing demanding games, but I can still hear audio

Recently, I've been trying to play games that I've previously had no issue running on my pc for hours. These include Destiny 2, Ready or Not, and Overwatch occasionally. When I play these games, eventually, sometimes almost as soon as I start the game, or a few minutes into a game, my monitors, both, at the same time, will go black, and say they have lost connection. Despite this though, I can still hear sound, both in the game and also from YouTube videos that I'm playing in the background. This hasn't been an issue up until about a month ago, and I've tried the following solutions to no avail:

Updating all drivers using driver easy and manually checking
Virus check and clean
Updating all of my games
Checking the temperature of my GPU and CPU (Both haven't reached any critical point)
Checking to make sure my pc can handle the power/voltage (it was fine, but I also wouldn't understand why it would be an issue randomly now)
I've unplugged everything and plugged it back in
I've tried some other small things and nothings worked so far.

My specs are:
GPU: NVIDIA GeForce RTX 3080
Processor: Intel® Core™ Processor i9-10900K 10/20 3.70GHz [Turbo 5.2GHz] 20MB Cache LGA1200
Motherboard: GIGABYTE Z590 UD AC ATX, ARGB, 802.11ac, 2.5GbE LAN, 2 PCIe x16, 2 PCIe x1, 5 SATA3, 3x M.2 SATA/PCIe
Powersupply: 1,000 Watts - Standard 80 Plus Gold Power Supply
SSD: 2TB GIGABYTE AORUS (PCIe Gen4) NVMe M.2 SSD - Seq R/W: Up to 5000/4400 MB/s, Rnd R/W up to 750/700k

^This is the Speccy info

As for testing it with just one monitor at a time, I just tested and I had the same results. Monitor blacked out, but I could still hear some sounds from the game.
