Please provide ALL the information requested in the wiki "How to ask for help" article. Don't forget to identify things that do not appear in the "load order", such as if you are using the FNV4GB Patch, NVSE and it's related plugins, texture replacements (specifically their larger image sizes: 1024x1024, etc.), and "post-processors" like ENB or SweetFX.

* See "How to markup images (etc) in forum posts and comments" article for how to use "Spoiler tags".

This assumes you have been able to at least get out of Doc Mitchell's house in a "vanilla, unmodded" game. If not, I recommend you read the entire "FNV General Mod Use Advice" article to understand the differences between this game and others you may have experience with; especially if this is your first attempt to mod FNV.

* Did you install Steam to it's default location? If so, please see the wiki "Installing Games on Windows Vista+" article for why the original default Steam behavior of installing games to the "C:\Program Files" folder tree was bad (they learned better, and don't do that any more); and why "disabling UAC and running as Administrator" is NOT sufficient, with instructions how to move it. This is the single most important thing you can do to fix and protect yourself against problems in the future. As much of a PITA as that is, it's never going to be any easier than now. System updates often cause issues with games installed to these folder trees. Please see the 'Restoring to "Vanilla"' section of the wiki "FNV General Mod Use Advice" article as well.

* Anytime the game "Crashes to the Desktop" (CTD) it's typically going to generate an error message in the Windows Eventlog. Please see the "Windows Error Messages" section of the wiki "How to read most Bethesda game error logs" article.

The following entries in the wiki 'Fallout NV Mod Conflict Troubleshooting' guide specifically address known Win10 problems:
* 'Issue: NVSE - fails to load after update KB4058043 to Win10 FCU (v1709)'
* 'Issue: Vanilla game Hangs on startup'; specifically "Cause-1" regarding DirectX9 drivers.
* 'Issue: "Full screen mode" exhibits CTDs and stutters or micro-stutters'
* 'Issue: Recent (post-Win10 FCU) CTDs after 10-20 minutes of play'
* 'Issue: Lag or "micro stutters" even with "New Vegas Stutter Remover" installed (or not)'. (Regardless of whether or not NVSR is actualy installed.) In particular "Cause-4" regarding video card settings. The latest video drivers may not be the best suited to an older game like FNV. All vendors drop testing of old games at some point. Backwards compatibility is never guaranteed, much less "optimization".
Also, "Cause-7" regarding "Superfetch" and "File search indexing". Windows updates will often reset these back on.
* 'Issue: Win10 Screen tearing in "Borderless Windowed Mode"'
* 'Issue: ENB Support for Windows versions later than Win7'
* 'Issue: Problems using ENB/SweetFx on Windows 10'
