Crashing before main menu

[A6MZero]

Having not played Oblivion in ages, I installed it recently and decided to install all my mods first on the fresh install; however, something is causing the game to always crash before the main menu. First it crashes on the Bethesda logo with the "Oblivion has stopped working" dialogue, but once the Oblivion.ini file is deleted it will get as far as the text loading screen before the main menu before freezing and becoming entirely unresponsive.

I've been installing with Wrye Bash, tried sorting my load order with BOSS and LOOT separately to try get it to work. I tried to use TES4Edit to try find conflicts, but I honestly not sure what I'm seeing (the files referencing things like what background colours mean are all apparently out of date, so no luck using that). None of those methods have shown me any obvious errors, and I'm really out of ideas beyond deleting everything, running a fresh install and going laboriously through every single install at a time.

I never bothered with Wrye while modding Skyrim or Morrowind, so it is possible I've made an error with the Bashed Patch, but if I did I don't know what it is.

Any help would be appreciated, been trying to get this to work for quite a while.

In case anyone has a similar problem, the cause of the CTDs at start was that the "Battlehorn Castle Upgraded" mod actually replaces the DLC .esp file with an identically named file; this was incompatible with the UOP for Battlehorn, causing the crash. Thankfully, my game has now graduated from CTDs before the Main Menu to CTDs when trying to start a game.
