Hi I searched the internet and forums and found nothing about the problem im having. I install the game, it runs fine, I mod the game, it runs fine, I reboot pc, the game crashes instantly when i press Start in the launcher. If I delete all files manually and redownload the game it works again. Deleting oblivion.ini does nothing so does changing thew obliviondefault. Game modded or no it still happens. So let's assume the game is not modded. What is interesting I delete references to bik videos in my ini so they dont load when the game starts. But when the 'bug' happens sometimes instead of crashing instantly it starts playing one of bik videos, 1 sec of music then crashes. If i delete all bik videos game goes to loading screen after movies and then crashes. It looks like after restart it is loading another 'default' ini? Can't figure it out. Windows 10, newest drivers, checked with older, I play Oblivion on this rig every year. It always worked. The only thing what changed is Windows. Now it's 10. It worked on Vista,7 and 8 with no problem. On 10 it works just fine too if I don't restart my pc. No crash logs, no nothing. If anyone have any idea, please let me know.
