Crash Code 0xc0000005

[flerbergerber ●]

So I recently started playing Oblivion again, and of course, like any elder scrolls game I play, I gotta mod the elder scrolls out of it and make it more interesting and realistic. I went mod crazy, and installed about 50 mods when I first started. I also have every(?) official DLC. Surprisingly, I had no conflicts and was able to play with minimal crashes. However, as time went one, I added more and more mods. A few days ago, I went crazy and added about 10 more mods, increasing my total to almost 100. Upon crashing on startup, I searched the logs, removed conflicts, and retried. Now with almost 15 less mods, I ran the game again, and decided to start a new character (The game started correctly this time.) I made a character fine, went slightly through the main quest, and decided to do the Siege of Kvatch quest. I got to the point where you open the gate for the other imperials and fight tons of scamps (By the way, the game spawned a freakin' Flame Atronach here. At level 2. Rude.) All was well until I killed a scamp. I crashed the second he died. I reloaded the game. Crashed again, this time I crashed immediately when I loaded the save file. Removed tons of mods, was able to get back to the save file, and started playing again. Killed a scamp, and crashed. Reduced tons of mods, still crash. I see no major conflicts, and OBMM doesn't detect any mod conflicts, so I see no problem. Event Viewer gives the following log:

Googled the exception code and heard that it was an out of memory error. Got no way to find out if that's true since Oblivion hates alt-tab, but I'd imagine Oblivion doesn't use up much RAM at all.

As of now, my mod load order is as follows:

Is there any way to remove these crashes while removing a minimal amount of mods?

I suspect that at this point, that save file is messed up somehow, and removing more mods isn't going to eliminate all of your problems. If it were me, especially with this little time invested in the character, I'd restart every time I try out a different combo of loaded mods. I know it sounds annoying, but you're already going through a lot of trouble, and for me, the peace of mind of not having a corrupted save would be worth it.

That code is the Windows_Error_Trapping for "Anything Goes." The pointer isn't one I've seen before.
It's an Access Violation which means the stacks have blown, - or as you mentioned, out of memory.
There's a lot of NPC activity during the Siege of Kvatch which can hit memory usage and FPS. The UOP in the load order should be just after the ESMs. Have you sorted with BOSS?
Also a post on Evrae's Alternative Start echo at Nexus claiming it's not compatible with Better Cities.

Do you use a lot of Hi Res textures? Reduce them.
Also check that you run the LAA patch with an appropriately tweaked ENBoost, OSR, Moreheap.

It can also point to physical HDD, SSD, physical memory fault. I once had it in the form of a BSOD on a now (almost defunct) computer. No doubt on googling, it comes up with any number of programs notably IE & Gimp, many of the recommendations are for re-install OS etc. probably replace H/W.
Doesn't harm to run chkdsk & mdsched to rule that out.
