Here's the fix list I'm going by, not completed in this order:
-------------------------------------------
1. Unplug all USB ports. (PS Eye, gone. Recharging cord, gone.)
2. Turn off internet connection to PS3. (wireless connection off)
3. Delete old install and let Fallout:NV reinstall (whiped and reinstalled)
4. Delete all save, trophy and install files from Fallout 3 (transferred to thumb drive and deleted from PS3)
5. Delete all save files from alternate characters on Fallout:NV (transferred to thumb drive and deleted from PS3)
6. Never turning on Pip Boy Radio or light (done, and in sound options turned radio off)
7. Turning off auto-save (check)
8. After every major event, quest, fight, etc. wait/sleep for 72 hours so the game resets characters and objects (will do)
9. Don't play for more then 5 hours straight. (I'm guessing I won't be able to, but ok, I'll bite.)
10. Cross your fingers. (and toes)
UPDATE added another step:
11. Turned off music as well.
Wish me luck!
