Hi guys i downoload pepper companion and many faces normal and zjay megaton hairs i i give this mods to fallout new vegas then my falloujt didnt work when i start to play there is black screen and nothing later is happening pls help

What's your load order? And have you tried disabling the mods and running it after that?

@paczkins069 Hello, see in my ig, troubleshooting FNV and try a selective loading. Before you can try to sort your load order with LOOT, it may change everything. Good hunting

1.My fallout works good before i put this mods in fnv folder
2.Yes I disable

Well, if you disable the mods, maybe try to verify the game cache (while the mods are inactive) and see if that will let you launch the game again. Verifying the cache might mess up mods that make ini edits, but it might be good to see if you can get the game running again without the mods installed

Also did you try Disabling and re-enabling the ArchiveInvalidation in the mod manager?

1. Arcades i do this 2 times and nothing happen
2. Hoppyhead i do this nothing happen

I would try to move some game saves somewhere else, I've heard an excess of saves *can* mess with the game a little bit. I would also suggest, because you have disabled your mods, maybe looking for any leftover files from manually installed mods in your data folder and moving it to see if that might help. If you have an ENB, try disabling it. I would also suggest trying out the 4gb FNV mod to see if you are out of memory or something.

i didnt try this but i have 4gb and i dont have enb

Just reinstall the game

nothing change this is nonsens

I have to say, at this point I would just reinstall the game as Blake_ said. Once you uninstall it delete the leftover folder incase there are some random files still in there, and if that doesn't work I have no idea what's wrong.
