This is the unoffical log of the people that have issues with The Elder Scrolls: Oblivion crashing. If you are having a problem with the game crashing please post your system specs and symptoms that occur when the game crashes.
Please report your crashing/unplayable/uninstallable symptoms to here. This log will be updated with as much information from Bethesda or Nvidia as we hear from them.
When attempting to fix your crashing problems, the Unofficial Oblivion Technical FAQ a good place to start.
Update 1 Wednesday, March 21 2:00 AM EST 167f
From reading the comments here and on other forums, one crash trend seems to appearing. People are reporting a crash to desktop when opening doors and/or when loading. I will be posting more information related to this soon.
Update 2 Wednesday, March 21 9:15 AM EST
If you are experiencing crashes when opening doors and/or when loading, you might want to try the following steps:
Update 3 Wednesday, March 21 12:00 PM EST
Nvidia has released their latest driver 84.25 today. You can download it here. It hasn't fixed my crashing issues, and at this point I really didn't expect it to. It seem that us unlucky users will have to wait for Bethesda's to issue a patch.
Update 4 Wednesday, March 21 3:38 PM EST
I tried disabling my Creative Labs Live! sound card and switching to the integrated RealTek sound on my motherboard. This hasn't fixed the my crashing problem, but it's still a good idea to include a description of your soundcard.
Update 5 Thursday, March 22 8:45 AM EST
I swapped videocards and put in an ATI 9800 Pro 128 MB and the game still crashes. I've added my Intel 875P chipset to the report list.
Update 6 Friday, March 23 6:15 PM EST
Today I fixed Oblivion's random crashing problems on my main gaming rig. To fix the random crashing I ended up uninstalling all but the most basic audio and video codecs. Here is how it's done, but be warned, if you don't know what you are doing you might trash your OS.
You will see a list of installed codecs. In my case the list was rather large, because I work with audio and video files a lot. You'll need to figure out which codecs are third party codecs for yourself.
You also might want to try this piece of software to help you remove codecs.
After you follow the above codec removal steps, reboot your pc and run Oblivion. Hopefully your crashing problems will be fixed.

Contributer yoyoo suggests disabling codecs, while Marc reports that he fixed his crashing problems. Marc's solution was to remove video codecs as well, only he did it by uninstalling a conflicting program. This approach might work out for users who are afraid of using the steps outlined in update 6.
Update 8 Friday, March 31 11:00 AM EST
Alun reports sucess in fixing his crashing problems by disabling some video codecs and CD burning software. He also provides a link to a Microsoft Help and Support page about default video codecs for Windows XP SP2.
I want thank everyone so far who has contributed to this log, and thank Bethesda for making Oblivion, which will probably go down in history as one of the best video games ever.
