Wow, that is a horrible experience!

It does sound like something is overheating. Have you watched the temperatures of the CPU or GPU? You can get CPUID HWMonitor to monitor temperatures for everything and see if there are any culprits. 

You could check and make sure your RAM is seated properly and run an exhaustive memory check overnight with memtest86. 

Make sure the video and everything is seated and plugged in properly. Look for any wires that are pinched behind the motherboard or anywhere else where they could be intermediately grounding and causing a shutdown. 

I’m not sure if it’s overheating. There’s been times when I turn the computer on in the morning and it shut down within a few minutes.  Plus I did check my temperatures regularly and nothing seemed out of the unordinary.  A while back I did try the memory test, and it shut down at some point so the test couldn’t be completed.  I will open it up again and check for the wires and as far as I know everything looks clean in there.

I would not be surprised if it turns out to be a failing PSU. I had a similar problem except my R10 would reboot. Then when the PSU gave up the ghost the fans would go full blast when I powered it on. I had it replaced under warranty.

Have you tried the PSU self test? You press the button on the back of the PSU. If the LED turns green it’s good.

You can buy a quality PSU.

Feeling overwhelmed and frustrated with all the constant issues that I have been having with my Aurora R10. I purchased it in January 2021. Started having constant problems in November 2021 when my computer started shutting off randomly. After numerous calls to Dell Support, they finally agreed to have me sent it in for repair. After a lot of stalling from Dell, I finally received my computer back. When my computer arrived back, one of my hard drives was broken during the time that Dell was working on it. They replaced the hard drive and the computer worked with some issues here and there. A couple of days ago, my computer began shutting down again. I called Dell Support yesterday and they did some updates, but this morning my computer shut off again. So when the shut off occurs the monitors are turned off the computer is locked and the fans on the computer kick in at full blast. The only way to turn off the computer at this point is to hold down the power button for a few seconds, or unplug the power source from the back. This occurs at random times and is triggered on its own. Sometimes I’ll be working in Photoshop or other times I will just be on the Internet. It’s even occurred when I had no programs running in the computer was just idling. I emailed Dell and now they are saying that this is not covered under warranty and I’m at a complete lost. Here is a link of a video I made this morning showing what happens.

what components do you have in your Aurora R11 . . . CPU, graphics card, PSU, RAM, etc.

liquid cooled CPU or air dried?

have you checked CPU & GPU temps when shut-down occurs?

First off I made a mistake, I have an R10 not an R11.  

AMD Ryzen (TM) 7 3700xX (8-core,32MB L3 Cache, Max Boost Clock of 4.4ghz)

NVIDIA GeForce RTX 2070

High-Performance CPU Liquid Cooling and 550W Power Supply

I haven't checked the temps when it shuts down as it happens at random times and I probably wouldn't be able to see it  before it shuts down.  However, this has occured a few times when I start my PC first thing in the morning.  If it were a temp issue, I don't see how it could overheat that fast.

Here is the info about the RAM.

Kingston HyperX Fury 64GB 3200MHz DDR4 RAM CL16 DIMM Black Single Stick Desktop Memory With Low-Profile Heat Spreader

Not sure if it's related but I noticed the speed is at 2400MHz, when I know I have 3200MHz.  

If there's any other info I can provide, please let me know.  Thanks

The 550 watt PSU should be sufficient for the 65 watt CPU and 175 watt graphics card. There was a time when users were having a problem with that small PSU, but usually with higher wattage components. You can use CPU-Z to check the frequency at which you RAM is actually running. You may need to enable an XMP profile to get your 3200MHz. When your rig is idling pop into AWCC and check the CPU and GPU temps. If you have a bad mount or inadequate thermal paste on your CPU or GPU, they will heat up pretty quickly. That is one reason a computer will shut itself down; to prevent damage. We should eliminate that as a reason for your issues.

I don't like where your R10 is located, the left side vents are air intakes and it kinda looks like if that right monitor runs alittle warm its blowing into the machine through the bottom vent on that Left panel. I don't think it's causing the shutdown issue but I would atleast move the machine away from the monitor so it's not trapped with air flow. 

Also Photoshop is a beast and I would run that program like running a game which is in High Performance Mode and Thermals set to High Performance also. 

Funny you mentioned this. I actually moved everything closer together to try and capture the shutdown so you could see it happen with both monitors and the computer all in the shot.  But, yes I normally have it spaced out a bit more.  I will set everything to High Performance Mode and see what comes of it.  Thanks

First its NOT SHUTTING OFF power is still on.  Its crashing to black screen of death. Second you don't mention if the os is on M2 drive or HDD.

I would recommend removing the GPU and testing the system with a speedster 105.

XFX Speedster SWFT105 B09Y7358KJ

Is this the original OEM RAM that came with the R10? I do not remember CL16 for OEM RAM, usually it is CL 22.

Also, 64 GB using a single memory module is not a validated configuration: R10 validated memory configurations 

Ok black screen of death that’s good to know. The OS is Installed onto a M2 drive. Thanks

Another thing that’s may help is that you must run a program called MSI Afterburner for your GPU fan control to keep the temps in check. Alienware doesn’t give us any gpu thermal options. It’s a must have program for the gpu.

Slots used reflects '4 0f 4' . . . so I'm pretty sure it is 4 x 16GB modules.
