The information on the website will probably be more updated than either the topic or this wiki page.


===Hardware tips===
==Deletion of page contents==
 
'''Update:''' It has been brought to my attention that some of the fans of my crash prevention guide are getting confused by the fact that there are two different versions of this guide available on the web. I was informed that the fan in question thought that this wiki page is the more updated version of my guide and described the website as "'''...a chopped-up copy/paste of an older version of the page I just mentioned''' (ie this wiki page-[[User:JdeRau|JdeRau]])'''...'''". Source: [http://en.wikipedia.org/wiki/User_talk:C2Talon 1] [http://en.wikipedia.org/wiki/Talk:The_Elder_Scrolls_IV:_Oblivion#Add_site_which_prevents_crashes_and_bugs.3F 2]
* Upgrade your computer, especially RAM! Oblivion is a relatively demanding game and if your computer is not up to scratch, you will find that your game, under enough strain, will miss pieces of code or give up. Also, Oblivion has a nasty habit of storing all the data it needs to load and never releasing it from memory. This causes crashes when your memory gets too full. Note that more RAM will only make this problem appear later though (A method of almost completely removing this problem is provided below).
 
* Did you know that you can find your PC's specifications by following these instructions: Click on "the Start button on your taskbar => Run". In the box that appears, type (without quotes) "dxdiag". In the system tab of the window that appears, write down the information you see next to "Processor" and "Memory" in the "System Information" box. Then click on the "Display" tab. In the "Device" box, write down information next to "Name" and "Approx. Total Memory". You have now got your PC's (game important) specifications.
 
* Remove dust build-up from your computer every once in a while. Dust restricts airflow and prevents heat from moving away from your components. The best way of removing dust is to use pressurised air to blow the dust away. Brush the dust off non-electronic components (eg, heatsinks) then earth it (touch against computer's PSU while plugged in and mains switched off).
 
* Regularly update your hardware drivers.
 
* Overclocking can cause game instability. Oblivion is very sensitive to overclocking and can become unstable even if other games work perfectly well.
* HP software has been reported to cause problems with Oblivion (?). Turn off your printer and exit all HP related software.
 
=== Windows Vista ===
Even though it has been out for more than 2 years (and Windows 7 is on the horizon), people still have problems with Windows Vista to this day.
 
Unless you need DX10 for other games (Oblivion doesn't take advantage of it), want the security or want the other useful features in Vista, you're probably better off sticking with Windows XP. If you are having problems with Vista, [http://www.tweakguides.com/VA_1.html Tweakguide's Vista Annoyances] article might be helpful.
 
One tip that will probably fix all your problems is to not install Oblivion into the "program files" directory. Rather place it in another directory (eg: C:/Games/Bethesda Softworks/Oblivion).
 
===Latest Official Patches===
'''Patch Oblivion to the latest version available'''
This might seem an obvious thing to say but there are probably still people out there who use a version of Oblivion that is less than the latest available. Currently, the latest patch is '''1.2.0.416'''. You may check what version you have by navigating to your Oblivion directory (by default, C:\Program Files\Bethesda Softworks\Oblivion). Right-click on "Oblivion.exe" and click on "Properties". Click on the "Version" tab and you will see the version number next to, well, "Version Number".
 
If this number is less than 1.2.0.416, you need to [http://www.elderscrolls.com/downloads/updates_patches.htm download the 1.2.0.416 patch]. If your number is greater than 1.2.0.416, you are either very friendly with Bethesda or something is wrong with your game (maybe a crack).
 
You need the latest patch because Bethesda provides numerous bug fixes and crash prevention measures and most mods are built around this patch, meaning that you might experience bugs or crashes if you use a mod requiring 1.2.0.416 and you use something less than this.
 
===Oblivion Tweak Guide===
'''Read TweakGuide.com's [http://www.tweakguides.com/Oblivion_1.html Oblivion Tweak Guide]'''  
The owner of this site, Koroush Ghazi, provides some valuable information on how to tweak your game to perform much better and crash less often. It is highly recommended that you visit this site and read Koroush's valuable guide.
 
While you're there, you should see if he has written a tweak guide for any other games you might own (Fallot 3, Morrowind, Mass Effect, etc).
 
Also make sure you read his "Tweakguide Tweaking companion" and his ATI Catalyst Control or Nvidea Forceware tweak guide.
 
===Mod Problems===
(some of these were suggested by '''BattleTooth''' of the Bethsoft Forum)
 
* The best way of preventing mod problems is to make sure your mods are working properly and are compatible from the moment you acquire and install them.
 
* Try to get the latest versions of your mods. These often contain bug fixes. Also look for compatibility patches if you have two mods which change the same thing.
 
* Use [[TES4Edit]] and [[TES4Gecko]] to clean and check your mods (only if you know how plugins work). TES4Edit is the preferred tool to use. Very easy instructions on cleaning using TES4Edit are found [http://www.uesp.net/wiki/Tes4Mod:Tes4View#Cleaning_a_Dirty_Plugin here]. TES4Gecko should only be used if you are impatient or a great noob. Instructions for using TES4Gecko are [http://www.bethsoft.com/bgsforums/index.php?showtopic=897105 here].
 
* If problems start occuring right after you install a new mod, deactivate it and see if the game still causes problems.
 
* Remove problematic mods.
 
* Defragment your hard drive, especially after installing a large mod. "The Oblivion Performance Project" provides some free or free-trial defragmentation utilities.
 
===Organise your load order===
There have been numerous bugs reported that are caused by an incorrect load order. This problem is relatively easy to fix. The easiest method is to use [http://www.tesnexus.com/downloads/file.php?id=20516 BOSS - Better Oblivion Sorting Software]. It will automatically sort most, if not all, of your mods into the correct order. For the rest that aren't sorted, you can use [[Wrye_Bash|Wrye Bash]] or [[Oblivion_Mod_Manager|OBMM - Oblivion Mod Manager]]. Wrye Bash allows you to directly input a date to set on the mod (load order is controlled by the date placed on a plugin) while OBMM lets you move a plugin up or down your load order one slot per click. Take your pick (probably best to get both).
 
===Use Wrye Bash===
The Bashed Patch, which is a feature of [[Wrye_Bash|Wrye Bash]], allows some simple mods to be combined together into one plugin, meaning that less plugins are being loaded by Oblivion. It also provides numerous small features which can replace entire downloaded mods, some of which are bug fixes and crash preventers (for example, the Bow Reach Fix, which prevents a crash caused by improperly configured bows, and an Nvidea Fog Fix, which tries to prevent the black-fog-like effect experienced by some/ most Nvidea users). It also allows certain features of mods to be combined together. Also, Wrye Bash provides a number of tools to repair specific problems in mods and save games. Overall, a very useful tool to have.
 
===Download crash prevention mods===
See below for a list of mods that attempt to prevent crashes and bugs from occurring in your game.
 
===Close background tasks, especially anti-malware software===
Background programs can cause problems with the game when they consume extra PC resources that could be used by Oblivion. See [http://support.microsoft.com/kb/331796/ this article] to find out how to start your computer with only necessary background programs.
 
===Disable autosave===
'''Disable autosave and don't use quicksave while in the same cell used to create the quicksave'''
There are stories around of how using auto or quicksave causes the game to crash. Quicksave only seems to cause crashes if you quick-load a game while you are in the same cell that was used to make the quick-save. Oblivion apparantly doesn't reset the cells when a quick-load is made so problems occur. The solution to this seems to be either leave the cell you saved in before the quick-load or restart the game. Autosaves definitely seem to cause problems when an exterior-interior switch is made. If you now need an autosave alternative after diabling the autosave, There is a solution provided below.
 
===Reduce System Overload===
Try to make your game less demanding on your PC - The less the game demands from your PC, the less likely the game is to crash or miss some code. Or so that school of thought goes. This is probably the last step you should take due to the probable lack of importance and results. This step may be implemented by either reducing your graphic quality settings or downloading a mod or tool which reduces the quality of something. Even if you don't plan on reducing quality, it might be useful to download some of the performance enhancing mods which don't affect visual quality significantly so that you can crank up some of your graphics settings further. For methods and mods which improve performance, I point you to [http://www.bethsoft.com/bgsforums/index.php?showtopic=881204 "The Oblivion Performance Project" thread].
 
===Other Ideas===
'''If nothing else works, visit [http://www.bethsoft.com/bgsforums/index.php?showtopic=561101&st=0&p=8103705&#entry8103705 Bethsoft's Unofficial Technical FAQ]''' - This thread provides a greater list of tweaks and fixes for the game than this page. "Why don't I just go straight there?" you might ask.
 
Firstly, this wiki page provides the information in an easier-to-read way.
Second, the Bethsoft thread is a more general Oblivion issues thread while this page is specifically for crashes and bugs.
And lastly, the information in Bethsoft's thread that isn't here is small pieces and the thread tends to repeat itself.
 
==Crash Prevention Mods==
This is a list of mods which aim to reduce or prevent crashes and bugs.
 
===The Unofficial Oblivion Patch===
[http://www.tesnexus.com/downloads/file.php?id=5296 The Unofficial Oblivion Patch v3.2.0 by QuarnAndKivan] - If you only ever download one mod for Oblivion, let it be this one. This mod fixes a HUGE number of bugs which Bethesda never fixed. The full list of fixes can be found [http://baldurdash.org/TESOblivion/UOPFixList.html here] (note that it is about 550KB of text). They report that they have fixed over 1800 bugs. If you have Shivering Isle or any of Bethesda's official plugins, you might also want their [http://www.tesnexus.com/downloads/file.php?id=10739 Unofficial Shivering Isles Patch] and their [http://www.tesnexus.com/downloads/file.php?id=9969 Unofficial Official Mods Patch]. The bug fixes are listed [http://www.baldurdash.org/TESOblivion/USIPFixList.html here (shivering)] and [http://www.baldurdash.org/TESOblivion/UOMPFixList.html here (other mods)]. Reported fixes are over 200 in Shivering Isles and around 220 in all the other plugins.
Please note however that these three unofficial patches all require the official 1.2.0.416 patch to work properly.
 
===Streamline===
[http://www.tesnexus.com/downloads/file.php?id=10400 Streamline v3.0 and 3.1 by Jagatelesin] - This mod does three things.
First, it clears your memory of unneeded files, hence improving performance and reducing or eliminating the overfilled memory crash mentioned above.
Secondly, it dynamically changes various graphics options based on your framerate. If your PC is struggling, Streamline will lower your graphics settings and raise them when your PC can handle it.
Lastly, it provides an overhauled autosave feature for if your game does crash. This system of saving has the same effect as using the save game function in the pause menu so it bypasses the quick and autosave function.
 
There are 5 downloads provided on the Streamline link but you should only worry about versions 3 and 3.1. Higher version numbers are usually regarded as being better but there are some people in this community who think that v3.1 actually causes more crashes than v3 does. I recommend you download and try both to see which performs better on your system. If you want more information on this mod, you will have to download it and read the readme. This mod requires [http://obse.silverlock.org/ OBSE (Oblivion Script Extender) v0012 or later].
 
===WeOCPS===
[http://www.tesnexus.com/downloads/file.php?id=22282 Windom Earle's Oblivion Crash Prevention System by, guess who, Windom Earle]  - This OBSE plugin tries to stop the game from crashing when something goes wrong with the code (Windom calls it a "crash offset"). I have not tried out this mod yet but it has received very good remarks so I must assume that this mod does what it is supposed to do. It makes Elys' Crashshield mod obsolete so if you use that mod, you might want to get weOCPS instead. Also, Elys' Crashshield and weOCPS can't be used at the same time. This mod requires [http://obse.silverlock.org/ OBSE (Oblivion Script Extender) v0012 or later] though higher is recommended.
 
===Fast Quit===
[http://www.tesnexus.com/downloads/file.php?id=22410 Fast Quit by Scanti and Skyranger-1] - this OBSE plugin lets you quit the game without the game crashing, giving the game a chance to save it's ini file and it makes the quitting process much faster. I have personally used this mod and I can vouch that this mod does what it is advertised to do. Before using this mod, my game would crash on exit nearly all the time. The Oblivion ini file was also usually not saved which meant any changes made ingame were lost. Now that this mod is installed in my game, I have not had a single crash on exit.
If you use Deathless Aphrodite's Clean Quit mod, I recommend that you switch to this mod instead. The reasons being that Fast Exit doesn't require Pluggy (which is rumoured to cause crashes) and it is also more reliable than Clean Quit. DA also mentions in Fast Quit's comments that it makes her mod obsolete. Since I spotted that comment, I have not been able to find Clean Quit on this site, leading me to the conclusion that it has been deleted by her. This OBSE plugin requires [http://obse.silverlock.org/ OBSE (Oblivion Script Extender) v0016 or later].
 
===Oblivion Stutter Remover===
[http://www.tesnexus.com/downloads/file.php?id=23208 Oblivion Stutter Remover by SkyRanger-1] - This OBSE plugin tries to even out your framerate. It is slightly more difficult to install than most mods but the effort is worth it.
You first type in a minimum and maximum framerate for Oblivion to run at. If your framerate drops below the minimum framerate, the game goes into slow-motion. If it rises above the maximum framerate, Oblivion is forced to give up some of it's processing time, supposedly improving stability by allowing other tasks use of that processing time.
I have briefly used this mod. I am not sure about crashing but it has improved my experience with the game (try play with 1,5GB RAM; a P4 Celeron 2.6GHz and Radeon 9550. I sometimes want to pull my hair out). The slow-motion is slightly annoying but it's an improvement over the stuttering. Some people have also reported improved stability using this mod.
This plugin requires [http://obse.silverlock.org/ OBSE] to work.
 
===Oldblivion===
[http://www.oldblivion.com/ Oldblivion by Asp, Atomizer, Excors, CrazyDog and Tommionu] - This allows older graphics cards to run Oblivion and allows you to use lower quality settings. This can help make the game more stable. Note that, according to information on their website, Oldblivion only runs on versions 1.0 and 1.1 of Oblivion though this is uncertain.
 
==Known Crash Sources==
This is a list of mods that are known to cause Oblivion to crash excessively (or more often than necessary) and any known solutions or workarounds for the issues. Use at your own discretion.
 
* [http://tesnexus.com/downloads/file.php?id=23979 Pluggy v122 by Elys] - Pluggy v122 has been [http://www.bethsoft.com/bgsforums/index.php?showtopic=955774 tested and shown to increase the chances of a crash on an Interior/ Exterior switch]. This has been linked to the HUD component added after v91. If you are experiencing these kind of crashes, try downgrading to v91 or upgrading to v125b and see if the crashes stop (available on the same page as v122 above).


I mean seriously, it is clearly mentioned in the second paragraph that it is the website, not this wiki page, that is more updated but anyway, I have decided that the only permanent and surefire way of completely preventing confusion is to delete the information on this page.


If you want crash prevention information in future, the place to go is my website: [http://preventcrashesinoblivion.page.tl/ Prevent crashes in Oblivion], not this wiki page.
