Windows 10: Blank Screen, Loud Fan, Unresponsive PC

The above has been intermittently happening to me the past few weeks. I've found similiar discussions on here, with no real cause or resolution. I built my PC a little over a year ago, and have not changed anything since. Over the past few weeks I or my wife has been using it for various things web browsing, gaming when the display cuts out monitor remains ON, a loud fan noose comes from the case, and the computer remains ON. I had audio playing during one instance and it continued playing but got "stuck" and kept blaring one single sound. The only solution has been a restart. My thermals

Blank Screen, Loud Fan, Unresponsive PC

The above has been intermittently happening to me the past few weeks. I've found similiar discussions on here, with no real cause or resolution. I built my PC a little over a year ago, and have not changed anything since.

Over the past few weeks I or my wife has been using it for various things (web browsing, gaming) when the display cuts out (monitor remains ON), a loud fan noose comes from the case, and the computer remains ON. I had audio playing during one instance and it continued playing but got "stuck" and kept blaring one single sound. The only solution has been a restart.

My thermals are fine. My AIO LCD has shown CPU in the mid 30s C, GPU low 40s when browsing (54 when this happened while gaming). My case is not dirty or dusty (though I am going to give it a good blowout anyway). I will also check all my connections and make sure everything is seated properly. I am on the latest Nvidia driver (though this has been happening since the driver before, and maybe the one before that too). I am also up to date with Windows.

Any ideas how I can troubleshoot this further? I've seen some similar threads talking about PSU issues, though even while gaming, I don't think im having any power spikes to cause this. Could be GPU? Again, whole system is a year old.

**Edit: tonight I took out the GPU and connected to my integrated graphics. The same issue happened but no fans ramped up, meaning it was the GPU fans hitting max prior to this. This time, however, my monitor screen returned like normal after a couple of seconds. PC was functioning fine. I DID notice that my RAM RGB was no longer lit, and my AIO screen was mostly blank, yet all my fans were still lit. I use iCUE, restarted that, and everything started functioning normally. Not sure what any of this means, but hoping it helps diagnose this.

Unresponsive PC with black screen, loud fan noise, high temperature, when idle

About every month or two, when I leave my Windows 11 Dell desktop on, and go and watch some TV in the evening, I come back to an unresponsive PC with a black screen, with loud fan noises and a high temperature. The only way to regain control is to power down, and then reboot.

This has never happened when I'm using it, which is most of the day, every day.

I'm not running any intensive/software games or graphics, just Edge and Chrome browsers, WhatsApp for PC, and Outlook (Office 365).

I worry about this because, if this were to happen at night when I'm asleep, who knows what could happen if the PC keeps overheating.

My Dell XPS 8940 runs Windows 11 22H2 (automatically kept fully up-to-date) on a i7-11700 @ 2.50GHz processor, running MalwareBytes Premium, with a NVIDIA GeForce RTX 3060 Ti graphics card.

Can someone please tell me what is happening, and how I might fix this?

Thanks
