I also tried running it from obse_loader.exe but I get the same result. My mods and exact load order never gave problems on my previous pc. Bingo. I have two hard drives. C: is a 100GB SSD with my os (Windows 7 indeed) intended for more taxing games due to superior speed. Oblivion is a game that is nowhere near challenging to run on my pc, so to save space, I installed it along with my other older games on my standard HD of 1 TB. I made a \program files directory for these games specifically. I also tested the game when I first installed it, and it worked then. Only after installing OBMM, OBSE, wrye bash, mods, etc. did the game start to hit puberty.
