Types of Mods
Tes4Mod:PCS Library/All distant (lod) objects turn black

Problem
All objects in the distance turn black.

Cause - Bloom Settings
This could be evidence of a problem with the game's bloom settings.

Solution: Try turning off bloom or switching to HDR.

Cause - Bad/Missing Far NIF
When the surface of an object appears all black or without detail, it is usually caused by a corrupted or missing 'normal map' ( ) file. 
For distant objects this 'normal map' is provided by the ( ) file.
A bad or missing   file can cause the related distant object to turn black. 
A bad or missing   file can cause the related distant terrain to turn black.

Solution: Try uninstalling mods that install  /  files until you determine which is causing a conflict.

Tes4Mod:PCS Library/BSA content does not load

Problem
Content stored in a BSA is not loading.

Cause - Oblivion cannot find the BSA
Oblivion will not be able to load a BSA that is not registered in the game's configuration file or associated with some plugin. In a more severe case, the game would actually crash as a result.

Solution: See Loading BSAs. In summary: Either register the BSA in the   or rename the BSA to   .

PCS Library/Crashing after exiting sewer
Tes4Mod:PCS Library/Black, blue or grey screen facing a particular direction

Problem
The screen turns black, blue or grey when facing a particular direction. 

Cause - Driver Trouble
This problem could reflect an incompatibility with Oblivion and the currently installed driver for your graphics card.

Solution: Try updating your card's drivers.
NVIDIA Drivers
ATI Drivers

Solution: Try turning off interior shadows--an option in the Video settings menu.
Tes4Mod:PCS Library/Black Screen CTD in Exterior Cells

Problem
Black Screen or CTD in Exterior Cells.
The game screen turns black upon entering an external cell, or CTDs.

Cause - Bad shader
Bad shader implementation in the video card drivers, mostly seen on Intel GMA X3100 integrated graphics when using Windows 7.

Solution: Change the following values in the Oblivion.ini file:
bUseWaterShader=0
bUseWaterReflections=0
Tes4Mod:PCS Library/Black Screen or CTD entering Exterior Cells

Problem
Black Screen or CTD upon entering exterior cells

Cause - Bad Shaders
Bad shader implementation in the video card's drivers, mostly seen on Intel GMA X3100 integrated graphics when using Windows 7.

Solution: Workaround: 
Change the following values in the Oblivion.ini file:
bUseWaterShader=0
bUseWaterReflections=0
Tes4Mod:PCS Library/Black screen (only HUD visible)

Problem
The screen turns black; only the HUD and menus are visible.

Cause - Bad Fog Setting
This problem is caused by a fog setting being set at 0.

Solution: Apply an NVIDIA black screen fix.

Solution: Enable the NVIDIA fog fix in the   section of the Bashed Patch.

Cause - Video Card Drivers Conflict
This issue can also occur if there is some sort of conflict between Oblivion and the video/graphics card drivers.

Solution: Update your video card drivers:
NVIDIA Drivers
ATI Drivers

Solution: Sometimes, there is a bad release or support for the game has been dropped, and you need to rollback your drivers to try to find a good fit.

Cause - Overtaxed video card
This appears mostly on computers running Nvidia's Geforce 7xxx and 8xxx series video cards

Solution: Downclocking the video card and/or changing the video card's driver seems to fix this problem on most computers.

Solution: Disabling the HDR feature may help solve this problem.

Solution: Disabling AGP fast writes on AGP-based video cards may fix this glitch as well.

Solution: Setting "int shadows" to 0 solves this problem when using HDR (tested on a GeForce 8800 GTX overclocked from PNY).

Solution: Reset the game's graphics through the console.
Hit the tilde key (~) to bring up the console. Type "CAL" and hit enter. 
Hit the tilde key again.

Additional Information
Although this is mainly a problem for NVIDIA cards, there are mods for which this bad setting can cause glitches and other anomalies. It may be safest to just make sure the fog fix is checked in the Bashed Patch.
Tes4Mod:PCS Library/Black screen CTD before Oblivion fully launches

Problem
Oblivion crashes to the desktop quickly, before the game has even completely launched.

Cause - UAC Protection
Windows 7 and Windows Vista users have User Account Control (UAC) on by default, which prevents applications without administrator privileges from installing and modifying files. Oblivion has to modify a few files, such as its main configuration file, in order to work fully.

Solution: This issue affects many utilities for Oblivion, so the cleanest, safest method to avoid this and further related issues is to uninstall Oblivion and install Oblivion to a folder outside of UAC protection (i.e.,  ). The same applies to Steam, if Oblivion is installed through it.

Solution: It is possible to only disabled UAC protection on the folder in which Oblivion is installed. Since Oblivion and other mods modify  , you may need to disable protection on that folder as well.

Selectively Disable UAC ...

Solution: Another clean method (albeit a bit less safe) is to turn off User Account Control all together.

Tes4Mod:PCS Library/Black sky (day or night) upon loading save game

Problem
Black sky (day or night) upon loading save game

Cause - OBGEv3 or earlier
Shaders in use may not be hardware compatible.

Solution: Try other shaders, or uninstall the older OBGE and install  .

Cause - Incorrect 3.0 Shader
Use of the incorrect 3.0 Shader.  (See "Additional Information".)

Solution: Restore v2.0 shader file.

Cause - Corrupt shaders
The shader files have become damaged or corrupted.

Solution: Restore vanilla shaders, or download  .

Cause - Bad sky textures
Corrupt or Incompatible sky textures.

Solution: Try deleting your "Oblivion\Data\Textures\Sky" folder.  Use original files,   (cleaned up originals), or other sky replacers.  Don't forget to use ArchiveInvalidationRedirection.

Additional Information
bAllow30Shaders=0 - If set to 1, this configuration file option allows (but does not force) the use of Shader Model 3.0 on graphics cards which support it, namely Nvidia GeForce 6600 or newer, or ATI X1000 series or newer. This can potentially improve performance when using HDR rendering for example. Check your   file in your "\Documents and Settings\User\Documents\My Games\Oblivion" directory to see if your card supports SM3.0 next to the option '3.0 Shaders'.  Note however that even by enabling this option, Oblivion still appears to use 2.0 shaders (check the 'PSTarget' and 'VSTarget' lines in  ). In any case, if you have one of the cards mentioned above, it cannot hurt to enable this option. 

To force the actual use of 3.0 Shaders after making the above change, you will also need to view your   file, and on the last line of the file check which shader package it uses (e.g. "Shader Package: 13"). Then go to the game "\Oblivion\Data\Shaders\" folder and rename that particular package to something else (e.g. rename "shaderpackage013.sdp" to "shaderpackage013._bak". Now copy "shaderpackage019.sdp" and paste it back into the same directory, and rename this new copy to the package name your card uses (e.g. rename it to "shaderpackage013.sdp" in this example). This will force Oblivion to use the Shader Model 3.0 shaders in the game, which may increase (or reduce) performance and typically shows no image quality difference.  There should only be one such file renamed.  Restore any others. 

Note: You will lose the daytime sky by forcing shader model 3 if you do so without enabling HDR lighting. For whatever reason, you need HDR lighting for shader model 3 to work properly.  For at least some people, things ran smoother once they forced the use of the 3.0 Shader package.  Things weren't as choppy and performance was a tad better.
Tes4Mod:PCS Library/Blue screen of death after inserting disc

Problem
Blue Screen of Death (BSOD) after inserting CD

Cause - Bad Disc Burning Software
This problem can be caused by incompatible disc-burning software.

Solution: Uninstall your current disc burning software (i.e., Nero) and download updated or more compatible software.
Cause - Bad Disc Drive
This problem can come about in the face of bad optical drive firmware or driver configuration.

Solution: Uninstall the drivers for the disc drive, reboot and reinstall. Right-click on the device in the Windows Device Manager to uninstall the drivers. (The Device Manager can be accessed via the Control Panel, or right-clicking on Computer or My Computer in the Start Menu and choosing  .)
Tes4Mod:PCS Library/Blurry Textures

Problem
Some textures in the game appear blurry.

Cause - Missing Mipmaps
This problem is a result of a texture not having mipmaps, which allow it to be viewed at various sizes with less degradation in quality.

Solution: Change   to 'Large' in Video setting (via the   menu).

Solution: Notify the modder and ask him or her to re-save the file with mipmaps, or open the file in an image/photo editor (i.e., GIMP or Paint.NET) and re-save the file with the generate mipmaps option checked.

Tes4Mod:PCS Library/Bows cause crash (Oblivion Bow Reach Bug)

Problem
The PC or an NPC equipping a bow causes Oblivion to CTD or even force the computer to restart or shutdown.

Cause - Bow Reach Bug
This problem occurs when a bow being equipped has a reach of 0.

Solution: A number of mods address this problem, most notably, the Unofficial Oblivion Patch addresses this problem and many other bugs in the Vanilla game.

Solution: Wrye Bash's Bashed Patch contains a tweak that should correct this setting in all loaded plugins, not just Vanilla Oblivion's ESM.

Solution: There are smaller mods that specifically address this issue for Vanilla and SI as well: Bow Crash Fix by Quazzy for SI.
Tes4Mod:PCS Library/CTD attempting to load a 'clean saved' game

Problem
CTD attempting to load a 'clean saved' game.

Cause
Sometimes with Bashed Patch, a 'double clean save' is required.  See Updating Saves for the basic procedure.

Solution: A 'Double Clean Save' consists of:
# disable mod AND Bashed Patch
# load last save
# create new 'clean save' and exit
# leave Bashed Patch disabled, and re-enable mods as required
# load 'clean save'
# create new save and exit
# rebuild Bashed Patch
Tes4Mod:PCS Library/CTD during exterior-interior transitions

Problem
Oblivion crashes randomly during interior-exterior transitions.

Cause - Buggy OBGE DLL
This type of crash can be cause by the old, buggy OBGE.dll (used by mods such as Screen Effects).

Solution: Remove the buggy   and install Oblivion Graphics Extender. Only the Core file is necessary.
Cause - Pluggy
Certain versions of Pluggy can cause this type of crash, as well as a number of other types of crashes. 

Solution: Upgrade to Pluggy to version 125 or Dev 132.

Cause - WeOCPS
This is an alpha-state OBSE plugin, and most likely it will remain that way. The extent of its instability is unknown, but it is a possible source of crashes of this nature.

Solution: Uninstall WeOCPS.

Cause - Bloom lighting & Anti-Aliasing conflict
Both Bloom lighting and Anti-Aliasing are enabled in game's video settings.

Solution: Disable Anti-Aliasing.  Some users found they needed to disable both.  Some video cards can successfully enable Anti-Aliasing on the card itself but not in the game settings.
Tes4Mod:PCS Library/CTD on load (before main menu)

Problem
Oblivion crashes before the main menu loads.  May display a system error:
exception code: 0xc0000005,
possibly with exception offset: 0002b77f.
Additional Information
Error code 0xc0000005 is known as a generic "Access Violation", and is thrown when an application tries to access RAM that either doesn't exist or hasn't been allocated to it.  The program generating the error is often itself a victim of another program which has over-written into it's own address space, changing it's code or data.

Cause - Missing or delinquent master
If a plugin's dependency is loaded after it or is not present at all. In the latter case Oblivion will definitely crash. If the former does not cause a crash, it can cause other disturbances in the game.

Solution: Check for missing masters or delinquent masters to install or dependent plugins to move. Regularly rerunning BOSS and paying attention the plugin indicators in Bash after modifying your load order would help prevent these issues.

Cause - Bad INI setting
Bad values in the Oblivion.ini can also cause immediate crashes.

Solution: Regenerate Oblivion's INI file.

Cause - Outdated Bashed Patch
If the Bashed Patch's configuration is not in sync with your current load order, the result may be an early crash. This can be due to plugin being updated in, added to or removed from your load order. This can also occur when updating Wrye Bash or switching between using CBash and the regular version of it.

Solution: Rebuild the Bashed Patch (every time your load order changes).

Cause - Invalid Record in Distant Load Data
Again, if Oblivion requires a resource that is not present, which can happen at many stages of loading and playing the game, the result will be some sort of crash. Therefore, if distant load data depends on information in a mod that has been removed, a crash may result.

Solution: Rerun TES4LODGen.

Solution: Delete  .

Cause - Corrupt EXE or DLL Files
The original oblivion executable files need to be both present and uncorrupted.

Solution: Restore original exe and dll files from a fresh Oblivion install, such as binkw32.dll and Oblivion.exe

Cause - Shader Conflict
An invalid shader 3.0 has been specified

Solution: See the PCS Library entry PCS Library/Game Mistakes Newer Graphic Card's Capabilities

Cause - OBSE Plugin Conflict
An unused OBSE Plugin is causing a conflict

Solution: Uninstall any unneeded OBSE Plugins.

Cause - Codec Conflict
A codec is causing a conflict

Solution: See the PCS Library entry PCS Library/No music

Cause - File Permission
File security permissions may not permit it to be loaded, especially if it was downloaded.

Solution: Uncheck "blocked" in file's Properties General tab.

Cause - Account Permission
Possible permissions issue for the account running the game.

Solution: Ensure the account running the game has "Full Control" permissions into the folders containing the game and save files.
Tes4Mod:PCS Library/CTD when fast traveling with companions

Problem
Oblivion CTD's when using try to fast travel with companions following.

Cause - Unknown
The cause is as of yet unknown...

Solution: A possibly fix is to either not give companions headgear or take it away before fast travelling.
Tes4Mod:PCS Library/Cannot find new plugin after saving in TESCS

Problem
TESCS does not successfully create a new plugin when saving a new plugin.

Cause - UAC Protection
Windows 7 and Windows Vista users have User Account Control (UAC) on by default, which prevents applications without administrator privileges from installing and modifying files.

Solution: This issue affects many utilities for Oblivion, so the cleanest, safest method to avoid this and further related issues is to uninstall Oblivion and reinstall Oblivion to a folder outside of UAC protection (i.e.,  ). The same applies to Steam, if Oblivion is installed through it.

Solution: You can try to give TESCS the necessary rights by right-clicking on the launcher in the Oblivion folder and using the   option.

Solution: It is possible to only disabled UAC protection on the folder in which Oblivion is installed. Since Oblivion and other mods modify  , you may wish to disable protection on that folder as well.

Selectively Disable UAC ...

Solution: Another clean method (albeit a bit less safe) is to turn off User Account Control all together.
Tes4Mod:PCS Library/Cannot load save that depends on unavailable content

Problem
A brownish extension protrudes out of NPCs and/or items.

Cause
This may happen if a save file depends on information in a plugin that is not active in your load order. It is more likely that this will result from trying to remove a master file than a regular plugin. Another common situation is that the PC depends on unavailable hair, eyes or race from an unloaded mod.

Solution: See Updating Saves. In uncommon, unfortunate cases the save file cannot be salvaged without installing the referenced dependencies.
Tes4Mod:PCS Library/Character's faces look dirty in game

Problem
NPCs' faces look "dirty" in game.

Cause - Ugly Self Shadows
This can be an effect of turning on self shadows.

Solution: Turn off self shadows in Video settings, either via the in-game ( ) menu or the Oblivion.ini.
Tes4Mod:PCS Library/Choppy opening movie sequence

Problem
Oblivion's opening movie sequence is choppy.

This problem has to do with codec interference from incompatible codes. See PCS Library/Keyboard and mouse stop working shortly after loading a save for more information and possible solutions.

Tes4Mod:PCS Library/Clavicus Vile shrine quest freeze

Problem
The game locks up after completing the Clavicus Vile shrine quest

Cause - Unknown
Seems to be a bug in the game code, related to the item that is placed in your pack as a part of the quest.

Solution: Workaround:
See the Clavicus Vile Bugs on the quest page.

Solution: Install the Oblivion v.1.1.511 patch.
Tes4Mod:PCS Library/Crash when entering Sheograth Palace during The Prince of Madness quest

Problem
Consistent crash when entering Sheograth Palace during the main quest question: The Prince of Madness.

Cause - RGO Conflict
Some conflict with RGO.

Solution: Temporarily disable RGO until after completing this quest, and then you should not have further conflicts with RGO.

Cause - A-bomb Side Effect
This is a possible side effect of the animation bug (a.k.a A-bomb) that occurs after playing the same profile upwards of some number of hours (possibly 200).

Solution: If you use Wrye Bash, apply Bash's A-bomb fix to the save by right-clicking on the save in the 'Saves' tab and choosing the option from the context menu.

Solution: If you do not use Wrye Bash, download and run the Oblivion Animation Fixer.
Tes4Mod:PCS Library/Crashing after exiting sewer

Problem
Oblivion crashes after exiting the sewer, the exit of the starter dungeon.

Cause - Non-Existent Race
It could be the case that mod is trying to modify a non-existent race.

Solution: Try deactivating race-changing mods.

Cause - Weak Hardware
This can be caused by a low end or unsupported graphics card. See System Requirements.

Solution: Get a better video card or a machine that is better for gaming.

Cause - A BSA cannot be found
Oblivion is looking for resources that do not exist. A common example is when a user installs "Martigen Monster Mod" (MMM) without renaming the BSA.

Solution: Make sure all BSAs are either loaded with a plugin or registered in the Oblivion.ini. (See Loading BSAs for more information.)
Tes4Mod:PCS Library/Crashing trying to enter Bruma

Problem
Oblivion crashes when you try to enter Bruma.

Cause - LO Changes
Custom mods installed when the PC's Bruma statue was erected have been removed from or moved in the LO. This could be a race change, switch to or away from a custom race, or removing an item mod of an item that had been equipped.

Solution: Use the Bruma statue fix mods to try to kill and update the statue. Kill it first; then update it.
Download the Kill bugged statues.
Download Update my statue.
Tes4Mod:PCS Library/Crucifix Posed Actors

Problem
Dead characters float about an inch off the ground with arms outstretched to the sides in a "crucifiction" pose.

Cause - Game Bug
This is a known game bug, but it is purely cosmetic.  It does not cause problems in play.

Solution: Simply 'grab' the corpse and it will fall to the ground.

Solution: Use a mod with "de-crucify dead actors" feature.  Examples are: 
Auto-save and time by kuertee 
Streamline by Jaga 
In Streamline turn off the auto drop 'set SLKillCorpses to 0' entry and just use the manual key combination   if it causes conflicts with other mods.  Should avoid conflicts by not having Streamline constantly searching to drop the bodies.
You may need to edit one Streamline script:
 
This should prevent the dead count from increasing incorrectly.
Tes4Mod:PCS Library/Disc appears to be blank

Problem
The disc appears blank in Windows Explorer.

Cause - Bad Burning Software
This problem may be due to bad disc-burning software.

Solution: Try reinstalling or upgrading (or uninstalling) your disc burning software (i.e., Roxio, Nero, Inter Video).

Cause - Bad Optical Drive Drivers
It could also be the case that the optical disc drive itself has a bad configuration or drivers.

Solution: To reinstall your optical drive(s): Right-click on My Computer > Properties > Hardware > Device Manager > right-click on the device > uninstall

...then reinstall.

Solution: If the drivers are very problematic and affecting the use of other discs as well, it may be worthwhile to search Google or the maker's site for updated drivers.
