Aurora R16, reboots 1 minute and 20 seconds after loading Windows

Oh - I should add that the BIOS has been updated - running 2.10.1. This was done when it was released.

Turn of automatic restart and see what the BSOD message says.

It should provide some hints as to what might be the issue.

Also check windows event log to see if anything is logged.

If it's at the exact same time that it reboots, it's likely a driver it's loading that is causing a BSOD. It should boot into Windows without crashing when using safe boot, which will then allow you to check the event log and if it's a driver or piece of software allow to remove it.

I would love to do that @Vanadiel but I can't get to the place to turn off automatic restart before the computer reboots!

Anyway - Dell are going to send a guy out to swap a couple of things to see if the system then stops crashing, and if that doesn't work it's going back to them...

@JohnDotKay​ start up in the recovery environment, where you can turn it off.

Recovery Environment.

@Vanadiel​ Even that doesn't stay running long enough to make the change.

I did make a Linux boot media and booted from that - while that too does the reboot thing after a minute or so, it also reports a variety of CPU 10 Machine Check errors on boot, so I'm putting money on the processor.

The Dell technician is scheduled to visit tomorrow and he will be bringing a replacement CPU and motherboard, so we'll see what happens after he's swapped the hardware.

Given the same reboot (sometimes with a blue screeen error) happens when booting Windows normally, when booting from a Win_PE recovery disk, a created Windows installation boot media, and a Linux recovery boot device (for my backup software), and given this happens with a completely fresh install of Windows, I don't think it's the software... We'll know more soon enough.

Dell technician arrived today with a replacement motherboard, but no replacement CPU. He replaced the motherboard and updated the BIOS on it (it was supplied with version 2.8.0 !!), but the problem persists. I get another visit tomorrow for them to replace the processor. We'll see what happens after that visit!

Just to close out... engineer arrived today with a replacement processor... swapped out the old one, and the PC is now behaving itself again.

So... big question here is just how effective is the 2.10.1 BIOS at preventing issues?

@JohnDotKay​ It's only effective if the processor was not already damaged prior. For the damaged processors, there's no repair possible and they have to be changed out if they are faulty.

@Vanadiel​ If that is the case it would imply that the processor that Dell swapped in my PC a month ago was defective, as the computer was already on BIOS 2.10.1 before they did that swap... and it is the processor that was installed a month ago that has failed this week.

Needless to say I'll be watching the system very closely in the next month or so given BIOS 2.10.1 is installed and this is now the second processor swap that this system has had.

@JohnDotKay​ I am thinking that if you read the small lettering, warranty can be either new or refurbished.

So it is possible they swapped it with a refurbished CPU. Although you would think they would use a new one, but then again I don't recall CPU damage like with these Intel CPU's...

I get "new or refurbished", but defective is a different ballgame. If this one fails too, I will insist on new next time.
