Monitors lose input and Fans Max (Crash)

GeForce RTX 4070 Ti GPU
Intel Core i7-13700KF CPU
DeepCool Castle 240EX Cooler
32GB DDR5-5200MHz RAM
Gigabyte Z790 UD MB
LANCOOL II RGB Case
(3x) Pure Wings 2 120mm Fans
Thermaltake 850 Watts PSU
M27U -- 27 inch / 4K / 160hz
VG27 -- 27 inch / 1440p / 170hz

Somewhat at random, both of my monitors lose input and my PC fans max out. I can still hear the video I was watching or the discord call I was in when this happens. Sometimes I'm able to use keyboard shortcuts to navigate to Shut Down, but other times I need to hard reset my PC.

My first suspicion was that this was a temperature issue, but my PC is perfectly able to run Elden Ring at 4K without crashing. It can withstand a CPU burner & GPU stress test without issue.

Sometimes I can get through almost a full day without any crashes, but as soon as it happens, it is very likely to happen again soon. The crashes almost always occur within 5 minutes of launching a game or shortly after closing a game, but have also occurred when I open Chrome and start a Youtube video. If I play a game without crashes for over 5 minutes, it doesn't crash even if I play for hours afterwards.

The only other technical weirdness I've experienced is that when my PC is idle, every so often both monitors go black for a few seconds before being restored.

It's a very frustrating problem to diagnose. What can you recommend?

    Hello, Silent_Sputnik

    Welcome to Microsoft Community.

    Based on the information you provided and the web search results, there are a few possible causes and solutions for your issue:

    One possible cause is a faulty or overheating GPU. You can try to monitor your GPU temperature and fan speed using a software like [HWMonitor] or [MSI Afterburner]. If your GPU temperature is too high or your fan speed is too low, you may need to adjust your fan curve, clean your GPU, or replace the thermal paste. You can also try to update your GPU drivers, reseat your GPU, or test it in another PC to see if the problem persists.

    Another possible cause is a power supply issue. You can try to check your power supply cables and connectors for any damage or loose connections. You can also use a software like [OCCT] or [AIDA64] to test your power supply stability and efficiency. If your power supply is faulty or insufficient, you may need to replace it with a higher wattage or better quality one.

    A third possible cause is a software or driver conflict. You can try to update, roll back or reinstall the drivers, disable any unnecessary background programs, or perform a clean boot to see if the problem goes away (How to perform a clean boot in Windows - Microsoft Support). You can also try to scan your PC for any malware or viruses.

    If none of these steps work, you may need to reinstall Windows:
