Max -
Did you wipe all partitions off the drive to do the Clean Install I gave you at the top of my post?

If you followed those steps then there shouldn't be any of these problems, unless something subsequently added or modified causes it or the wifi or ethernet adapter is failing and needs replacement.
Note that that drivers steps are so important they are printed in red. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows drivers are rarely enough.
Let's start over and use these steps for troubleshooting install which will wipe the drive deeper to eliminate anything being left over. Then watch closely as you set it up for when the problems begin.
I will give you all possible steps to troubleshoot Windows installation failure which work in about 90% of cases. If not we'll go from there:
Follow the gold standard Clean Install steps in this tutorial which compiles the best possible install that will stay that way as long as you stick with the tools and methods given: http://answers.microsoft.com/en-us/windows/wiki...
I am the author of this Clean Install tutorial which has been used by millions of consumers in Windows 7 and 10, and popularized Clean Installs with consumers over the past decade. In addition I've helped troubleshoot tens of thousands of cases of install failure and never had one fail to get installed if there is close cooperation. So let's get started:
Make sure all other drives and peripherals are unplugged. Update the BIOS or UEFI firmware to latest, or reset to Defaults, making sure (if you have it) UEFI is enabled, CSM or Legacy BIOS disabled, Windows Boot Manager set first to boot, if necessary disable Secure and Fast Boot until after install, set SATA controller to AHCI, Save changes and Exit. Access BIOS/UEFI Setup as shown here: https://www.mydigitallife.net/comprehensive-lis...

Create the latest Windows 10 Installation Media by installing Media Creation Tool and following the directions here: http://windows.microsoft.com/en-us/windows-10/m.... If you're using another PC to do this uncheck the box for Recommended Settings to choose the exact version and bit rate for the target PC only.
Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor...
If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first. If you can start Windows enter UEFI firmware here: http://www.isunshare.com/windows-password/four-...
The media may also be bad, so confirm it boots and queues up per these steps in another PC, or else recreate it. You can also try a DVD, or the alternate download site from MS TechBench here: https://tb.rg-adguard.net/public.php. Burn to DVD using WIndows Image Burner or create bootable flash using one of the options here: https://www.tenforums.com/tutorials/2376-create...
Choose the boot device as a UEFI device if offered, on first screen press Shift + F10 to open a Command Prompt, type the following commands, each followed by Enter key:
DISKPART
LIST DISK
SEL DIS # (replace # with the disk # of the Windows disk from list in previous command)
CLEAN
EXIT
Close Command Box, on second screen choose Install Now, then Custom Install, then at the drive selection screen choose Unallocated Space, click Next to let it create needed partitions and start install - this makes it foolproof.
Make sure to follow the setup steps in the first link tutorial to complete your install. Drivers are important enough that those steps are printed in red. If installation stalls or won't complete, try disconnecting from the internet.
You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the first linked tutorial. It's a better install than any amount of money could buy and a great learning experience that will make you the master of your PC.
Failures and errors during the Setup phase can often be overcome by disconnecting from the internet, e.g. unplug router.
Please report back the results of each step so I know what else to suggest.
