you own a killer of a PC, a lot of people I help have much less of a beast and have come out on top to know it's the software that runs it all.
The real trick is getting the right software onto it and enabled. The desktop is IE, it represents the systems browser, for windows anyways so the systems updates.."Windows updates" are patches for older security flaws found of that very software.
the display is the heart of the system, the graphics drivers control all of it. All the patches run thru those drivers. So, in order to better control that environment, Windows fixes the holes "THEY" are responsible for and have admitted about.
install all updates, takes a bit of doing and a lot of time. When you run out of updates available, dig into what was installed, there are two updates that require every one to remove. windows 10 is exempt from this, but all other systems fall prey to these things.
(KB2952664) that is what we call a root installer, it installs this one (KB3035583), and these two combined are the Nag screens to upgrade to windows 10. both of these need to be removed. That is the push..the only thing is, that push does not include hardware drivers as the system is a business system. it's not a game console.
windows ten has a big big issue now, it, that kernel requires all software installed to have digitally signed and authorized signatures in the files, that includes all of their own products. Your graphics hard ware, if not owned in some way by them? required signed drivers to be allowed to install and remain.
A hardware issue, preventing OEM installs of graphics is not written in stone but falls under this scope / scenario.
Even some direct x files are Obsoleted by that OS. they get replaced with updated versions that reak Havoc on our games, become incompatible...even though they are-signed.? *'dll's get deleted and there is no thing that will tell you this took place other than it's own event manager, the logs on the system.
IF the hardware has an issue, windows WILL default with standard drivers, will not even install USB drives for 3.0 and up.
look in your device manager and see how many yellowed flags exist.
ix them first, get all drives installed, then use the Manufacture's device setup CD or downloads for that machines hardware and see if the new system will allow it to install.
In the long run ,Microsoft basically want's to start all over, only this time, the game changed, staying with 1 OS but manipulating whats in it.
If you know the exact problem ? that's where you start.
game diagnostics come around based on an assumption that the persons PC is optimal. we can not in all rights give advice based on bad installations or issues admitted too. it's not right, and the games require a good base to run on.
( SOLID GROUND ) not loose dirt. fallout 4 ? oh man, it needs every thing to be in tip top shape, almost perfect PC's run it ok.
complaints seen about issue to date posted here...show the problems are there..and later come out during discussions.
On systems Fo4 is installed on that are not up to snuff, way way too many posts reflect this and is Immediately seen.
the graphics settings tell the story, low verses the high..and in between...all tells the story.
Your time spent on the repairs will fix your run-time with the games and issues the games have with the mods will simply go away.
we can't fix that sort of thing with talk, it's real hard faults we can't see or match.this is up to you.
I hope things work out great for you in the future.
