recently, my oblivion crash a lot.
i get so frustated because i have to repeat what i'm doing again if it crashed without saving it first, and it sooo boring..

it not happening before.
i add some mod to the game (about 31 tipe of mod), i put it little by little at first.
like, put 3 mod then test it first, after no problem found, i put it again and again and again.
but after cople of test, finally i just put the rest of it (about 11 more mod) to the game, and test it out, its no problem at first but after some hours it goes crash.
and until now, its crashed after some minute of playing, and always crash when i minimize the oblivion (i had to set the game to windowed mode because of it).
and now, i really want to know what mod make that crash, and i dont want to test it one per one anymore.

What i want to ask is.
Is there any error log in oblivion?
If there is then where is it?, can't find it anywhere.

Is there nobody can help me??

There is no error log that helps one determine what mod was the cause of the crash - what you are doing (step-by-step approach) is the best way to install mods.

There are some other best practices to avoid crashes:
1) Use BOSS to sort your load order.
2) Use a mod manager to install/uninstall mods - use wrye bash or OBMM.
3) Use Oblivion Stutter Remover to help mods run better.
4) Use better hardware (not that practical). Best not to use high resolution textures etc. when your VRAM is less than 512 MB.
5) Use a program like Gamebooster to suppress background programs (Anti-virus etc) while playing Oblivion - and let Oblivion use most of your RAM.

That said, I am not sure if Oblivion runs well in Windowed mode - I think trying to alt-tab or minimize Oblivion is a sure-fire way to get a crash. Can you avoid doing that and play in full-screen mode? Maybe your problems will be resolved.

Crashing after a few hours is expected for Oblivion - your memory gets used up, and eventually there is a crash when Oblivion gets up to about 1.8 GB of RAM - you can avoid that ceiling if you have 64-bit windows architecture, and use the 4 GB -LAA patch.

Alright, the first thing i want to say is, thanks for your attention...

1) What is BOSS?? a tools to sort my mod load order?? can't OBMM sort it already ?

2) I have OBMM to install / uninstall my mod already..

3) Oblivion Stutter Removal?? never heard of it, maybe i can look it up on tesnexus...

4) I think my hardware already good enough to run oblivion smoothly.

I have :
AMD Athlon II X2 240, 2.80GHz processor
4.00 GB of RAM
ATI Radeon HD 4200 with 1.00 GB memory
And around 9.00 GB of page file.

and i run it just with medium video quality.
Or maybe, there is hardware conflict within oblivion and my hardware??

5) Indeed, i use game booster too and ram tuneup software (TuneUp Utilities 2009).

I can't avoid doing my alt+tab, because my profession sue me for doing it ( well u know, work stuff to do ).

this is the second time i install this game, i already play it around 1 years ago, with my old computer that far more low capabilities than this.
AMD athlon 1900, 1,65Ghz Processor.
768 MB of RAM
ATI Radeon 7200 with 256 MB memory.

but it run smoothly and very rarely to get crash, i even doing alt + tab too ( to see the console command ).

so thats why i really confuse about this problem.
last time i try with just activate only 4 mod, but its crash too..
or maybe i should reinstall the game??

but first i will try your recomendation first.
and one more thing what is " the 4 GB -LAA patch " you mention in the last?


Thanks again for reply my Question,,,,

Find explanations and links for these and more listed here: http://tesivpositive.animolious.com/?page=programs_and_utilities. Oblivion Stutter Remover details http://tesivpositive.animolious.com/?page=stabilization_and_optimization_mods and http://tesnexus.com/downloads/file.php?id=23208
I'd recommend installing BOSS - it auto-sorts your load order according to best practices - through OBMM you will have to do it manually, and chances are you will do it wrong. BOSS is not a replacement for OBMM, just a tool that works alongside OBMM.

Regarding the LAA patch, http://tesivpositive.animolious.com/?page=laa_patch. Note that this is useful only if you are using Windows 7/Vista/XP 64-Bit.

I would recommend reading other portions of the guide to increase your general knowledge about mods and tools.

About your Alt-tab problem, I don't know the answer - I am surprised you can play the game when working - Oblivion is a fairly CPU/GPU intense game, and doing any other program in the background is going to cause issues.

I am not sure why you were able to do it and why you cannot with this current PC - I have never used the windowed mode ever.

Trying to alt-tab out of Oblivion is a sure way to bring it down in a heap when you're using mods. The game's memory management system is not tolerant of page swapping to virtual memory.

You haven't specified your OS version, which would be helpful.

Ah, i forgot that..
I use Windows XP Professional SP2 32bit

I guess, i cant use the LAA patch right...

But i already try using BOSS and Oblivion Stutter Remover.
And i think it help, now my oblivion only crash when playing 20-30 minutes from only 5-10 minutes before using that tools..

There is a lot of useful tools in TES4Positive Guide.

Thanks For the tips...

From what I'm aware of, even when all the mods are working...Oblivion is bound to crash at some point. Even more so with a heavily modded Oblivion. Fallout 3 had the same problem (at least for me). Fallout New Vegas doesn't seem to have this issue, luckily. I don't think Morrowind did either. Even with mods that prevent crashes and what not, it still crashes after a while, even with a good PC. One reason this could be (at least in my case), is I don't think Oblivion uses more than one processor core...does it?

I have same problem as you though. Game doesn't lag AT ALL, and it runs very smoothly. But it crashes every 30 or so min, I'm lucky to get an hour in. I tried Oblivion crash prevention system a few months ago, Oblivion Stutter Remover and some other mods...but it still crashes every 30min. It crashes for vanilla Oblivion for me too, but not as much.

Here is my system:

Geforce 260GTX 896 MB
i5 Processor 3.3 Ghz
8gig DDR3 ram
Windows 7 64bit Ultimate Edition

Crashed when I had windows XP as well, game was unplayable in Vista (for me), and runs Oblivion the same as it did with XP.

Is this just the game's problem with having so many mods? I don't have as many as some other people I've seen. I use BOSS to order it (doing it manually svcks lol)...I probably have 75 mods? I'm not sure. Its around 75, maybe closer to a 100...in any case, I see some modders having 150+ mods, which is a lot.

Most of my mods add sounds, quests, new lands, monsters etc...I do have some graphical mods though. Qarl 3 Redimized, All Natural and some other smaller ones...I still get 60 fps out of the game. And it still crashes.

I'm wondering if its the number of mods that crash it, or if its just how the game was built. I don't get any graphical problems, and the crashes aren't specific, they are very random. I can never repeat them.'

My friend bought his game off steam, he doesn't download mods at all, and it crashes for him too. His PC is not the same as mine, not sure his exact specs, but its almost as good as mine, if not the same. He plays purely vanilla, nothing else, no sound mods, graphics mods or anything....and it crashes every 30min-1 hour for him.

In any case, when it doesn't crash, its definitely a lot of fun.
