I swear I've played Oblivion with mods before, but it's like I'm practically starting over again now, I'm so clueless.

I'm basically using just Fran's and the HGEC stuff. I have a few odds and ends like the actors carry torches mod and no psychic guard. I'm using the Steam version. I was just using BOSS and OBMM, but I tried using Wrye Bash as well and made a bashed patch thinking that might fix it, and it didn't. (For the bash, I just had the first thing clicked, Alias Names or something? I turned lock times off, did BOSS, then turned it back on.)

I crash sometimes as soon as I leave the sewer. Other times it's a few minutes later. I can't work out what's wrong.

I really hope someone can tell me what I'm doing wrong. I'm sure it's just a little thing somewhere, but I'm ready to give up.

Thank you in advance, and sorry for my cluelessness.

Try de-activating the "Bashed Patch" esp. I have experienced that this file often messup the game.

Otherwise:

De-activeat all at once, and run oblivion with each mod, one at a time to see wich mod makes it crash.

Iv'e just recently got back into modding Oblivion pretty hard. If you need some hands on help, you can add me on skype or gtalk (use my forum name) I have some pretty awesome tricks for smoothing out the modding process.

UOP Vampire Aging & Face Fix.esp, No psychic guards v1.2.esp - Use Wrye Bash tweaks instead these mods.

You should also be aware that Oblivion on PC is not perfectly stable on many systems even completely unmodded, and you're not using any stability mods as far as what you've listed. If you install OBSE and Oblivion Stutter Remover, you might find your problem solved without any other issues.

Also, the Bashed Patch will never cause any problems in and of itself unless it's built improperly (which is hard to do with such a small mod list). It's also absolutely necessary to make many mods play nicely together. You may also need to adjust your load order if you're not using BOSS, though it looks like you might be.

Thanks guys, I got it working!! I narrowed it down, and it was Fran's Chance of Optional Creatures that was doing it. I deleted that, and now everything works fine. So strange. I have no idea why that was causing the issues, but I don't actually want it anyway (so why did I install it? Who knows).

About the Vampire fix and Guards fix.... I am trying to find how I can do them in Wrye instead of using the mods, but Wrye is confusing. It's bad to use them tho?

Sorry, double-reply. Yep, I'm using BOSS. I can't use OBSE though because I'm using the Steam version.

I wanted to keep my mods really low. I was going to play vanilla since i still haven't played Shivering Isles, but then I really wanted to try Fran's, and I realized I wanted the body/clothing mods. Might use a distance mod as well.

I used to use FCOM and had no desire to try to get all that working. I am just not technically-inclined as most folks, and I'd spend more time messing with mods than actually playing the game.

OBSE works just fine with Steam. You just need to unpack the OBSE package into the main oblivion folder, start the game from the launcher as you're used to do and you're done.

Ah! I had no idea. Saw someone wrote it did not work and just assumed they were correct. So basically the Steam version works just as well as the retail version then when it comes to mods? Might have to get OBSE just for the stutter remover if nothing else.

Under Tweak Settings. They named UOP Vampire Aging and Face Fix and Crime Alarm Distance. Set Crime Alarm Distance to 1000.

It used to not work with Steam, then the Valve folks themselves provided a .dll to make it work, which is already included in the latest OBSE packages. See http://forums.steampowered.com/forums/showthread.php?t=900993
