I'm currently stuck without any idea as to what's really causing the issue. I'm currently back to crashing within 30 minutes as I attempted to delete all graphics drivers that could be present on my system in case they were trying to override each other and now I'm on the latest nVidia driver. Even games like DiRT Rally and Beam NG.Drive don't cause the fan to run high, but this could be down to poor optimization), so I rolled the graphics card drivers back and this allowed the game to run for nearly 2 hours before crashing (again inconsistent). Most of the time the system crashed without giving any errors within about 30 minutes (though the time wasn't consistent), though I noticed the graphics card fan wasn't running as highly as it usually does while playing SWTOR (it's the only game I have which does that. When this first started, I thought it may be a HDD issue as the system crash was a blue screen for 'unexpected_storage_exception', but that wouldn't always come up when the game crashed (and didn't under any other circumstance). None of these have solved the problem and it seems restricted to just SWTOR as no other game, even graphically intense with lots of in-game physics, cause any issue.

I've tried updating and rolling back graphic drivers (nVidia GeForce GT 545), reinstalling and setting exceptions in my anti-virus (Avira), dropping graphical settings to minimum and fully reinstalling the game following a guide to 'install properly on Windows 10'.

For the last couple of weeks, SWTOR has been crashing out my entire computer at seemingly random points as I've not been able to lock down a particular action in the game that causes it.
