Strange New Vegas save glitch

[fromach]

Trying this again in the dedicated New Vegas technical support forum, since the last thread probably got deleted for not being in the right place(I didn't realize how deep the categories went). I have two systems running New Vegas/TTW on my laptop(Asus Strix w/GTX 1070 and an M.2 card) and my self-built tower(AMD FX-8350; MSI RX560 Aero; 32GB Corsair Vengeance 2400mhz DDR3; Samsung 850EVO 500Gb M.2; ASRock 990FX Killer mobo) with identical mod lists and loadorders(barring maybe standalone equipment mods). I can save/autosave as much as I want on the laptop with zero problems, but my tower only allows me to save once normally before locking up for 2-3 minutes at a time. A quick look at the Performance tab of Task Manager shows that, during any save past that first save, the active time on my C: drive(the 850EVO) jumps to 100% and my read and write speeds drop to 0kb/s for the entire duration of the saving process, after which the game saves normally. This is the first time I have experienced anything like this since New Vegas was released and I am completely and utterly confused as to what would cause this. On both systems, Nexus Mod Manager, Steam, New Vegas, and all of the mods are located on the C: drive/M.2 card.

You may want to adjust your "file indexing" settings as well. Assuming Win 10, see this article on various settings you can adjust.

 

Not knowing how experienced you are with SSDs, you might want to view this article about some of the advice regarding them and how it has evolved over the years.

 

MS has been steadily tightening up control and access over it's "protected system folders". Each new update and patch brings differences. 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. Please see the 'Restoring to "Vanilla"' section of the wiki "FNV General Mod Use Advice" article as well.
