I recently got a new computer - Windows 8.1, 64-bit, Intel Core i7 processor, NVIDIA GeForce graphics card. Installed KOTOR2 and some mods on it... but if I play the game for any significant period of time, the entire computer will crash and I have to force shut it down and restart. I've tried turning the graphics options down some and running it in Windows XP compatability mode, but still no luck. I am still able to play the game, but the crashes are rather irritating and can result in lost progress.
I have the KOTOR Collection version of the game (1 CD) and am using the following mods:
-TSLRCM 1.8.4
-M4-78 EP 1.2
-SLM and Apostle Sabers Add-on (I don't see this listed in the downloads section any more - has it been removed?)
-Onderon Traveler Clothing (Got it from Gamefront, couldn't find it there, but it's at this link - http://www.gamewatcher.com/mods/star-wars-knights-of-the-old-republic-ii-the-sith-lords-mod/onderon-traveler-clothing-1-1)
-Newbiemodder's Korriban Expansion
-High Level Force Powers v2 and 2.1 Update (I believe I got this from the now defunct KOTORFiles)
-M4-78 Movies Remade (http://deadlystream.com/forum/files/file/572-m4-78-movies-remade/)
-Handmaiden 4 Females - Disciple 4 Males for TSLRCM 1.8.3 (Just realized that I have a different version of this than of the RCM, but that wouldn't cause a computer crash)
-Dustil Restoration (http://deadlystream.com/forum/files/file/343-dustil-restoration/)
-Choose Mira or Hanharr (http://deadlystream.com/forum/files/file/108-choose-mira-or-hanharr/)
-Combat Simulation Arena (not sure where I got this from, sorry)
So far, I have not quite yet made it to the point on Peragus where the Harbinger shows up (just need to finish obtaining the voiceprint for the airlock). If anybody has any ideas on how to fix this problem, I'd be very appreciative!
