Hi, so I'm new here, and I just bought Oblivion recently, like 2 weeks ago I was around 5 hours in, doing the "Spies" quest. Since I was a vampire, I had to wait before I left the cloud temple place.

I went outside to get to the wing across, when suddenly, my game crashed. It kept crashing after I loaded my saves. I haven't even modded my game yet. But when I started a new game everything started out fine. I decided to reinstall it via. steam. But when it was done, I started the game, tried to skip the Bethesda intro, and my game stopped responding, I had to Ctrl + Alt + Delete myself out of there.
I tried letting the intro run through, but after it got to the part where it shows the text (copyrights and such), as it started to fade black, it stopped responding again. I don't know what to do, could someone help me?
