Like I said, with Windows Machines, performace problems are often caused by Software, and blamed on hardware. Before spending a whole bunch of money on upgrades, or a new system, I'd adjust settings, clear out all the unneccessary junk, disable any popups, and defragment the hard disk. If you know how, you can also partition so that your game is quarentined away from the Adware, counter Adware, and Anti-counter-adware duking it out over your hard drive. Most of the crashes I experienced were ultimately caused by 1 program trying to convince me that my computer was infected. I finally had to System Restore, and defrag, then it never happened again, once I seperated it from Exploder. Also, I re-install skyrim after every update, that seems to make it a lot more stable, with fewer internal glitches. Don't worry, your save files are seperate, and backed up by steam, so you won't lose your progress. This allows the scripts to mesh better than retro-patching without a re-install. I am convinced that it is a combination of software and hardware issues. My problems began with crashes from Fallout New Vegas when I was using a different windows installation on another hard drive- also using gtx 460's in sli. I couldn't get that game to play stock either. I ended up installing windows on my smaller SSD, upgrading to a 7870, and overclocking/cooling my cpu. I was okay for a while after limiting the framerate (although I tried so many different things its possible I had something else modified), but I was getting smooth gameplay maxed out for a couple days. It's frustrating that I can't get back to that point, so I partially believe that I did have some other modification/fix that I can't remember. Problem is I don't want to experience another 30 more load screens and crashes of trial and error (half of the crashes result in a reboot). Have you ever used the backup inside of steam for backing up games? Or do you just copy the game folder? Also I noticed that every time I reinstalled Skyrim my gamesaves were reloaded, wouldn't those be dependent on mod's that I had installed that are no longer there, thus resulting in instability?
