I've got a relatively new PC with a 5090 GPU, but I'm facing this weird issue where my monitors flicker off and just stay off. The only way to get them back on is to hard reset my entire PC. Sometimes this happens once or twice a day, while other times I can go a whole week without it occurring. My entire setup is only about 3 months old. When the monitors shut off, I notice the fans going crazy, and while I can still hear audio, it eventually bugs out too. I monitor my temperatures, and they rarely go above 70C. Is this likely a GPU issue? Here are some specs:
- Processor: Intel(R) Core(TM) Ultra 9 285K (3.70 GHz)
- Installed RAM: 64.0 GB (63.4 GB usable)
- System type: 64-bit operating system, x64-based processor
- Edition: Windows 11 Pro
- Version: 24H2
- Installed on: 5/11/2025
- OS build: 26100.6584
- Experience: Windows Feature Experience Pack 1000.26100.234.0
If you need more info, just let me know!

It sounds like your fans are kicking into high gear when the system freaks out. This usually indicates that there might be a communication issue between your hardware components. In some cases, people end up replacing hardware when this happens. It could be worth looking into if everything is seated correctly and trying to reset the BIOS settings as a first step.
Have you checked your PSU? It's crucial to know if it's providing enough power, especially since you're running a 5090. Make sure it’s the right wattage and meets the necessary specifications. If you're not sure, I recommend checking the label on the PSU or looking it up online.
I believe it's supposed to be around 1200W with 11.5V 80 PLUS Gold rating, so it should be good!
