Weird Crashes for No Reason

[LesbianPaladin]

On my longest save file, every time I live the Casino you meet Benny in the game crashes, no matter what. I've tried disabling several mods that might have done it, with nothing working.

Then, when I tried a new save file, it was okay for a short while before crashing every time I tried to get from the goodsprings saloon to the gas station to talk with Ringo.

This is my mod list:
FalloutNV.esm
DeadMoney.esm
HonestHearts.esm
OldWorldBlues.esm
LonesomeRoad.esm
GunRunnersArsenal.esm
ClassicPack.esm
MercenaryPack.esm
TribalPack.esm
CaravanPack.esm
YUP - Base Game + All DLC.esm
Interior Lighting Overhaul - Core.esm
Interior Lighting Overhaul - L38PS.esm
FCOMaster.esm
YUP - NPC Fixes (Base Game + All DLC).esp
MWCC [standard].esp
WMIMNV.esp
Weapon Retexture Project.esp
ILO - YUP Patch.esp
MojaveExtended100.esp
MojaveExtended20.esp
MojaveExtended40.esp
MojaveExtended60.esp
MojaveExtended80.esp
EVE FNV - ALL DLC.esp
FCO - GlowingOne.esp
The Mod Configuration Menu.esp
FCO - NPC Changes.esp
FNV Realistic Wasteland Lighting - All DLC.esp
NevadaSkies.esp
Interior Lighting Overhaul - Ultimate Edition.esp

Please help!

You should always start troubleshooting from any error messages you can see. (They are your best "clue"; and why they exist at all.) Reporting such messages accurately is an essential first step.

Anytime the game "Crashes to the Desktop" (CTD) it's typically going to generate an error message in the Windows Eventlog because the game engine was not able to predictably handle the error. Please see the "Windows Error Messages" section of the wiki "How to read most Bethesda game error logs" article.

Logs generated by the game itself (not Windows) are found in the game folder, where the "FalloutNV.EXE" file is located. They generally have the ".log" file extension, or a filename with "_log" in the name and a ".txt" extension.

 

All of the following may not apply to your specific situation, but are worth repeating anyway.

* Be aware that one error may mask a number of other errors, which will not appear until those masking them have been resolved. Building a stable game consists of resolving each problem individually until none remain, and then realizing that every change you make thereafter (including updates to mods already installed) run the risk of introducing new problems. Be prepared to revert to a previous save if you do so.

* Did you install Steam to it's default location? (GOG is not a problem as it places the game correctly.) 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" or "C:\Program Files(x86)" folder tree was bad (they learned better, and don't do that any more but didn't change it for older games); and why "disabling UAC and running as Administrator" is NOT sufficient, with instructions how to move it. Among other things, later versions of Windows (since the game was released) force files in "system protected" folder trees to be "read only" regardless of how you set them manually. It includes instructions on how to correctly move the Steam folders out of that folder path.

Don't move it to a folder under "User\Documents" either, as "executable" files are not permitted to run from there for similar "anti-malware" reasons.

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. With the game moved out of the default location you will not need to be running it as an "Administrator Account", which is safer. Please see the 'Restoring to "Vanilla"' section of the wiki "FNV General Mod Use Advice" article as well.

 

Please see 'Issue: CTD after 10-20 minutes of play (post-Win10 2017 FCU)' and 'Issue: CTD without warning, "Out of Memory error", or stops responding after the Main Menu' entries in the 'Solutions to "Crash To Desktop" (CTD) problems' section in the wiki "Fallout NV Mod Conflict Troubleshooting" guide. Note the default NVSR settings do not work with Win10, but there are some recommended by the author for Win10 further down in the article.

:* Currently, the recommended alternative to NVSR, if you are running Win7 or Win10, is to try using the "New Vegas Tick Fix (NVTF)" and "New Vegas Heap Replacer (NVHR)" mods instead. However, until NVTF includes the option, you may want to continue to use NVSR for the "iThreadsFixedToCPUs" setting. Note though, use of NVSR along with NVTF is unsupported.

* Related to the NVSR problem, for problems AFTER a save game is loaded see also 'Issue: Incomplete save game load' in the "Troubleshooting" guide.

* Don't install every optional file for a mod. Read the install instructions carefully. Optional files need to be selected on a "case by case" basis. For example: with any mod you usually only need one ESP (and possibly one ESM) "base" file depending upon whether you have all the DLCs active or not. Only if you don't have them all active do you need to install any specific DLC versions if there is an "Ultimate Edition/All/Merged DLC" version.

You only need one of these:

MojaveExtended100.esp
MojaveExtended20.esp
MojaveExtended40.esp
MojaveExtended60.esp
MojaveExtended80.esp

 

In the meantime, please see the 'Vanilla Load Order' entry in the 'First Timer Advice' section; as well as the 'Towards Game Stability' and the 'Common Game Problems' sections of the wiki "FNV General Mod Use Advice" article.
