Jeez pal. I’m waiting to hear back regarding a replacement pc, but after reading your experience I think maybe I should just get a refund while I’m still within the window. This company has gone downhill

Yeah, best practice IMHO when there is a defect within the 30 day window is return for a refund and repurchase.  Note that if you do a warranty replacement it can be replaced with a refurbished PC (as opposed to a brand new PC) at Dell's discretion.  If that matters to you, it may also be something to ask about before accepting a replacement. 

"Dell, at its sole discretion, may dispatch a replacement part to you, arrange for you to send your product or defective part back to Dell's repair depot or replace the part or product with a comparable part or product that may be new or refurbished."

@r72019  more like return and shop somewhere else. Tech support is terrible. Might as well look at other vendors.

Agreed.

I also think these bad machines and Out-of-Box-Failures should be re-captured by Dell and examined (to see what went wrong so quickly).

During that initial test/break-in period ...  I try not to mess with it a whole lot (no immediate hardware upgrades). Just do a basic setup, install minimal programs, and just use to normally to make sure it's reliable and stable. 

Might as well look at other vendors.

Like who exactly?

For fairly high-end retail pre-built gaming systems ... not much else out there (unless you want to use one of the higher-priced boutique shops). But those are more like a custom-build than a retail pre-built.

New Aurora-R10

- was doing the necessary updates and such. 2 hours into use I received a blue screen.
- Tried restarting it and the r10 seemed to be stuck in a boot loop.
- spent nearly 4 hours on the phone with them only to be told that it was probably a bad motherboard.
- Installs the new motherboard (weeks later) and the r10 is still stuck in a boot loop.

====================

I hope you get it worked-out.

Sounds like your original problem was just a minor BIOS setting or corrupt Windows. Even if Windows-10 needed to be reloaded from scratch, it's a 45 minute job with SSD installed.

It would be nice if Dell went back to sending on-site Technicians that actually did some trouble-shooting when required. I think it would cut down on mis-diagnoses and over-compensation of problems with new machines in the field. I still recommended it when I have Dell's ear.

Unfortunately, I think the time for that has come and gone. Now-days, only "fast-and-easy" solutions are ever considered for accepted problem-resolution work-flows.

@Tesla1856 @Ibuypower, cyberpowerpc, omen. I’ll even wait out the parts shortage. These issues are not something a customer should be dealing with when paying $3000 or more for a machine. Iam currently literally being ghosted by support just trying to find out status

"Finally received the replacement which was an r12 because they didn't have any r10s available. I open it up and plug it in and it won't start."

So what happens when you push the power button?  Flashing amber lights or nothing at all?

If the latter check that all the cables including the power cable are fully inserted on both ends.

"Could you try the following:

Try to access the recovery environment, turn your computer on and off three times."

The OP said the problem is he can't turn on the PC.

The boot loop problem was on the pc that got sent back.

Could you try the following:

Try to access the recovery environment, turn your computer on and off three times. While booting, make sure you turn off the computer when you see the Windows logo. After the third time, Windows 10 will boot into diagnostics mode. Click Advanced options when the recovery screen appears. Click Troubleshoot and choose Reset this PC, follow the screen instructions, and wait until it's finished.

If you do not require any files that are stored on your current system, you could try the option mentioned here 

You would select the option "Reinstall Windows 10 to the Dell factory image using recovery media"

This should not require a bootable USB, if I remember correctly. Just access to the USB stick.

ok, I got confused because I was reading the last message from the OP, where he described he could not boot from the USB to reinstall the OS. 

Now the title of the posting makes more sense. My bad.

For the not being able to turn on the replacement (R12), there's a few things you could try.

1. The power supply should have an LED light and a test button. When you plug it into an outlet, without turning the computer on but with the power supply switch on the power supply turned on, there's a small button next to the power supply LED that you can press. That should perform a diagnostic on the power supply and the LED should be green.

2. If 1 turns out ok, then you could try pressing the power button on the front of the Aurora, and it should display no amber flashing codes. If it does flash amber codes, this is what they mean: System Diagnostic Lights 

If you get any amber lights under item #2 could you post the code(s)?
