For about a week I've been working with BOSS, tes4edit, wrye, and OBMM to try to set up a heavily modded working Oblivion.

Please, if you reply, understand that I have 0 knowledge of programming, and I am a novice at using any of the above mentioned programs. Apologies in advance for my lack of technical know-how.

This is my load order (all dirty edits have been cleaned in tes4edit and I have no idea what could be causing the problem):

What are your system specs i.e cpu, graphic card etc etc? And at what point does the game crash? From which location to where? Or is it consistent for all locations? Did the game start crashing from the beginning of modding your game or did you add a mod and it started crashing after? How did you install your mods? Did you install all bunched at the same time (not recommended unless trying to restore your save files) or one or few at a time?

You would be far better posting your load order with Wrye Bash so we can view the version of the mods used.
Also re Oscuro's. Are you using the lite version? I ask because your employing so many of the optional plug-ins that you would be better running the full version, of which these add-ons are included.

edit - and that's not an extensive load order by Oblivion modding standards

System Specs: win 7 ultimate 64, intel core i5-2500k cpu @ 3.30ghz (4 cpus) ~ 3.3ghz, 16384 mb ram, AMD radeon hd 6900

Game crashes on any fast travel to any location in the middle of the loading bar. It says "ding" (crash sound) and CTD's.

I did not test crash on fast travel previously, only exiting sewers (since it had been a problem before). Any one of the mods could have done it.

I install mods one at a time if they're complex such as AWLS and II and Better Cities, then test it (again without fast travel). After every mod I sort with BOSS and rebuild bashed patch if readme says to do so.Yes, I am using lite oscuro's so I have the option to use Enhanced Economy instead of Living Economy.Wrye load order is below. Also, I would love to be able to use a REAL extensive load order, but the more stuff I add the more unstable it gets. I am a mod addict and it's worth it to me to learn how to do this right.

Okay did you apply the 4GB patch to your Oblivion.exe to utilize more system memory? Are you also using fast exit and/or Crash Prevention System (although some users might recommend not using these two plugins)?

Oh about adding more mods, you are not alone brother. It's normal for the game to be unstable when you add tons of mods into it although you shouldn't go over the limit of 255 ish.

I'm not sure what patch you're talking about. As for fast exit and/or CPS, I've used them both separately and neither addresses this issue. Something is dreadfully wrong and I think a fresh install might be needed. :/

Good to know I'm not alone with the instability issue. Oh, and it's sister!

Check to see if you have an anti virus program running or some other background program. Use gamebooster. That would be a start.

As this only happens on fast travel, it has to be specific to that function. So, the CTD happens when you fast travel to ANY location or specific ones? How about using console to coc (try coc testing hall).

Next, drop all you possessions and try to fast travel (in case something about them causes an issue).

Install a travel mod (like cyrodill travel service) and see if that also CTDs when travelling.

Try deactivating all your mods except Oblivion, start a new game and see how it goes. Get Alternative start mod to test without the tutorial dungeon.

These are all long shots but may tell you more about the problem.

Thanks, I'll try all those things. I guess I'll post whether or not it worked later. This all seems like great advice.

Oh my bad I meant sister . The patch you could download here http://www.ntcore.com/4gb_patch.phpbut only if your system memory not graphic memory is at least or more than 4GB and with 64bit OS which you're using.

Yep, should be all set, I have about 16gb of memory. Thank you so much.

I'm unfamiliar with ANB_No_FastTravel but it seems a strange one to use if you are trying to fast travel. I can't imagine this not causing a problem related to your crashes.
I'd also very strongly suggest to update your version of Oscuro's to version 1.34 full http://www.gamesas.com/topic/1320382-relz-oscuros-oblivion-overhaul/ and rid yourself of the numerous add-ons which are included in the full version.
If as previously stated you want to use Enhanced Economy simply ignore the option for LE when installing OOO.

edit - also remove OOO-Level_Normal.
Oblivion XP completely replaces the games normal leveling process making this plug-in redundant.

Well, ok, I guess I could do that. I just really didn't want the Living Economy.. blech. x.x
