Windows 10: Windows 10 LTSC with i9-9900K fails to boot - bootloop

I have three identical builds with the following components numbers in bold are ebuyer quick codes:


Main HW:

Intel Core i9 9900K CPU 859394

Hyper 212 Air CPU Cooler 288855

Motherboard Gigabyte Z390 UD 861445 BIOS Updated to latest version F10c

WD Blue SATA 1 TB SSD - 2.5" 801062

Corsair Vengeance LPX 8GB DDR4 QF:743023

Corsair 750W PSU 429987

120mm Case Fan QF:882187

2 x 80mm 3-pin Case Fan QF:442844


PCI Devices:

PCI Express - RS232 Card QF 239719

1251.100 CIFX 50E-RE Ethernet I/P Card

2 x Camera Grabber GigE Card AdLink PCIe-GIE74, 4-Port, PoE


I have installed the Windows 10 LTSC edition on all of these PCs, and found that the PC rebooted at different stages of setup i.e. Region, Keyboard, Network etc.


I moved the SSD to a different build to complete setup and then the PC reboots when it reaches the logon screen.

The PC can boot in Safe Mode, and does not reboot automatically. I left it in safe mode for 1 day and had no problems. As soon as you attempt to boot in normal mode, the boot loop happens again.


I have performed a memtest and that was successful. The PC remained switched on at the summary screen for 3 days without any restarts.


Disconnecting all of the PCI cards and fans does not change the situation.


Can anybody offer any advice as to what might be the issue please? The PCs are already very late for delivery and I have no idea what to try next...

Amazon (USA) - my default price checker for me. I meant to link them.

i9-9900K - $474.99. Price dropped from last post. BTW I paid $519 for mine in Feb.
Ryzen 9 3900x - $732 - $829 - Buying Options

 

i9-9900K build

Hello guys (and gals), been a while since I posted. Anyway, I got this for my 60th birthday last week….



and the end result is this….




System specs....

• Case - Cooler Master HAF X case
• MB - Gigabyte Z390 Extreme
• CPU - Intel i9-9900K
• RAM - 32gig Corsair DDR4 Dominator Platinum RAM (3333MHz)
• CPU Cooler - Corsair AIO CPU cooler – H115i Pro
• Drives - 5 Samsung SSD drives: 2x 512gig 970 NVMe drive (OS & Photos drive), 1 x 1TB 850 EVO (Acronis backups), 1x 1TB 860 EVO (music), and 1x 2TB 850 EVO (Games, data).
• Graphics card - Sapphire Tri-X R9 Fury
• Sound - On-board (ESS Sabre HiFi using Realtek drivers)
• Optical Drive - LG Blu-Ray
• Power Supply - EVGA Super Nova I000 P2 (1000 watt)
• OS - Windows 10 Pro x64 (1809)

You can see the wire management here. And for those For those wanting a closer look at this board see this 7 minute . It's expensive, but you get a lot with it. Anyway now I'm just awaiting AMD’s board partners to release their versions of the Radeon VII for the graphics card upgrade.

In the meantime I’m seriously considering replacing my HAF X since I had to modify it to hold a 280mm AIO at the top of the case. Two cases under consideration, but with concerns are...

1) Cooler Master’s MasterCase H500M seems a good choice but being my MB is an extended (E-ATX) board, I’m a little concerned about it’s wiring clearance as discussed in this .

2) (more wishful thinking) is Corsair’s Obsidian 1000D. Plenty of room even with a custom water-cooling setup. Issue is size, and initial cost of ownership. I don't have a place to sit it, and in addition to the $500 (499.99) dollar asking price, there’s the added cost of RGB fans, and custom water-cooling parts.

Honestly, this Corsair 1000D is probably more pipe dream than reality considering cost and size. That said, assuming quality name brand parts, what is the average cost of a custom water-cooling setup? What’s the maintenance of such a system like?

Thanks

Hi,
From this post of mine it shows even the 3800x @ 4.4 is not doing so bad cheaper and beating 9900k *Smile
