So I just installed Oblivion, added 2 mods that aren't DLC (Beautiful People and Male Body replacer) and every time I start Oblivion the game crashes after the initial Bethesda screen when it first starts to load. I have Oblivion installed to C:\Games\Bethesda ect. Any ideas whats causing the problem?

Does the game launch without mods? Have you installed the latest official patch? Please, first try to launch the game with only Oblivion.esm activated.

Also, try regenerating your Oblivion.ini - http://tesivpositive.animolious.com/?page=know_how_to#RegenerateTheOblivion.ini
