So after hours of scouring the wisdom of the internet, I have finally caved and decided to try my own cry for help. Up until recently, I have always played Fallout 3 on my PS3/Xbox, but I have decided to try it out on my PC. After all, I loved playing Oblivion with mods, so surely I'll enjoy Fallout with them just as much. So I start the game, and the first 2-3 hours go as smoothly as can be expected from my rig. It's not designed, really, to run games, but it can run Fallout at medium to high quality just fine with minimum stutter. So I get out of the Vault 101, head to Megaton and mess around that area for a while, and then try to save my game. I get a crash. I thought "Hmmm...Weird" but just kinda glanced over it and booted the game back up. Same thing happened after attempting to exit the area I was in. Eventually, I had established that my game only crashes when it tries to perform a save of any kind - be it autosave or regular save. I know this because I disabled autosave and played the game for a good hour or so and did not have a single problem. But, of course, once I tried to save a gain, it crashed. So I ran off to the internet and started digging for clues to my problem. Unfortunately, I've never managed to find a permanent solution. There were times when it seemed like the game fixed itself for no reason, but then would start crashing again a few hours later. I really want to play this game on PC, but this problem is really killing it for me.

Here's a list of everything I've already done, just so we aren't wasting any time here:

Uninstalled/re-installed Fallout 3 - several times.

Installed Fallout 3 in C:/Games folder instead of Programs x 86.

Uninstalled and re-installed all my mods.

Running Fallout 3 in Windows XP Service Pack 2 compatibility mode.

Edited my INI file, both in My Games and Fallout 3 directory.

Installed d3d9.dll into Fallout 3 directory.

Created a merge patch for my mods using FO3Edit.

Installed Fallout 3 4GB Enabler mod.

Uninstalled some of my larger mods to free up some space.

Loaded a prior save before loading my actual save.

Loading my save game twice.

Killing myself/blowing myself up after loading my game. (This one seemed to be doing the trick for a while, but now seems to have stopped working altogether.)

So, if anyone can help, please do. Many thanks in advance.

P.S. As a slightly less important problem, lately my game has been blue screening my computer when I use my PS3 controller to play it. This is very recent, and if anyone knows why, I'd appreciate an answer, although I can live using a keyboard and mouse...I think.

First off why did you have to create a new thread. I will post my notes from the previous thread.

Thanks for posting the load order.

Do you have the issues when using a new character playing without any mods.

Also having that dxdiag report will help us out a lot.

That is most likely a driver problem, though it could be a hardware problem with the controller. Try reinstalling the drivers for the PS3 controller, or swap the controller out for another one (if you have an extra).
