I have a GTX 580 and a 750TX which is rated for 60A on a single 12V rail. This is not a hardware issue; that much I am certain of. My PC is 100% stable for days under every stress testing application as well as PSU (CPU+GPU) stress tests. http://torch.earth-616.com/sigpics/Rig.png

Did you try what I posted above?

Permanent fix for crashing on my PC: It is related to auto-saves like gjm777 stated. However disabling auto-saving is insufficient (and not required; leave auto-saving enabled as it was). I noticed that once the game started crashing, if I fast-travelled to another location, it said "Autosaving" and after a few minutes in the new location it crashed. However after I rebooted and clicked Continue game, it started from my old location and not from the auto-save after I fast-travelled, which meant that the auto-saving failed completely and it subsequently crashed. So I fast-travelled to a new location and created a manual save (Escape->Save) and then quit to desktop. I then went to the "My Games\Skyrim\Saves" folder and deleted all the auto-saves and quick-saves and left only my manual save. Now when I continued playing everything worked fine including future auto-saves and it hasn't crashed in over 2 days. I had inadvertently done this 2 weeks ago while trying to clean all traces of the game and it started working properly back then, so it's worked successfully on two incidents. Basically: 1. Continue game 2. Fast-Travel to new location 3. Save game manually (Escape->Save) 4. Quit to Desktop 5. Delete all saves from "My Games\Skyrim\Saves" except your manual save. 6. Continue game.

I am not having any more crashes with the v1.4 update. However sometimes there is severe graphical corruption after playing for a couple of hours. I just quit and restart the game. There is also corruption if I alt-tab out and come back.

Yesterday I was able to play for 2 hours without a crash until I voluntarily quit (on official patch 1.4).

I have concluded that Skyrim causes a severe graphics driver crash and corruption in the GPU that persists even after a warm reboot. This is entirely possible since Creative sound card settings such as Stereo Surround/Xpand persist even after a warm reboot into ANOTHER OS such as Linux or Mac. The hardware isn't completely reset after a warm reboot. If you attempt to play another game after a Skyrim crash reset, it will also crash within seconds/minutes. However if you power off the mains for a minute and then cold boot, everything else will be stable again. You can even play Skyrim for minutes or hours until it crashes again. I never had even a single crash in Skyrim until about 3 days into the game. Thus I believe it's related to the size of the save file, just like the PS3.
