Windows takes two hours to boot every reboot. Goes to spinning circles

@axe0 what do you read out of this from Event Viewer?

Code:

Please correct me if I'm wrong, I've seen those kinds a lot but always ignored them (scrolled too fast)
I believe the first is a log that simply says 'some problems with the CPU drivers', the second is the performance state of the CPU frequency.

I have a feeling there could be more going on than we might think. @RobH2, when you're booted please open control panel, click 'system' item, click 'Advanced system settings' at the left side of the screen, click 'advanced' tab, in the part 'Performance' click the button 'settings', click 'advanced' and click 'change' in the part of the virtual memory. Please make a screenshot of the settings of the virtual memory and post it.

Crash dump initialization failed!

Hi everyone, I'm back. Just catching up on all the activity. To recap what I've missed:


WHEA_UNCORRECTABLE_ERROR (124)
Hdwre failure or driver problem which makes hdwre appear as failed

bucket 0x124 PCIe
What other PCIe devices are installed besides Quadro GPU?

Safe mode works fine.

Need another Disk Management screenshot.

Remove all items from startup (except Defender; AVG has been uninstalled previously)

Update system specs as much as possible

In 2 of 3 crashes the USB 3.0 eXtensible Host Controller is returning, in the third it is the Nvidia GPU.

System never "actually" BSODs, yet we have crashes in the data. ( This was my suspicion - the system *is* crashing, but trying to recover - and eventually does, but it takes 2 hours - and Rob never sees an actual BSOD screen!)

BIOS flashed with 3-8-16 update

MEMTEST+86 will not be needed at this point.

Kyhi's rescue disk is at the ready.

Visual Design Studio is throwing errors (from an old demo?)

Uninstall Daemon Tools, Visual Studio and all ASUS software (ASUS update will not uninstall-*.msi file missing) - done in Safe Mode with Revo

Try pulling kbd out immediately after boot process

Update USB drivers from ASUS website (2 of 3 crashes in 1st 10 seconds are relating to the Intel USB controller driver)

Unable to install USB driver update in Safe Mode.

Enabled Boot logging, went into a normal boot - waiting 2 hour now for results.

Check for firmware update on the SSD

Event Viewer: Collaborative processor power controls on processor 0 in group 0 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware.

Waiting for a screenshot of the settings of the virtual memory once into normal desktop OS

Based on time stamps, it appears we have about 1 hour to go...assuming the boot time is consistent now.

Thanks guys for all your help! :)

Several hours ago, we considered removing the Quadro from the equation and using the integrated graphics - is that a step we want to add in here at some point?

EDIT: There is a way to install drivers using command prompt. Although, now that we are waiting for a boot to normal desktop OS, I guess that won't be needed.

Also, essenbe wanted to know if you have a spare drive, in case we need to try out something he has in mind.

@simrick, according to his system specs, he is running Xeon's and I don't believe they have on board graphics.
