I am having some extremely weird Oblivion problems. I just picked up the GoTY a few days ago, and I am not happy. First, here are my specs:

W7 64-bit
4gb ram
slightly overclocked 8800GT
Core2extreme q9650 4.0
230 gb hd
DX is updated
Drivers are updated

First, I'd like to say, before I even started playing Oblivion, I modded. Just because I've heard so much about the Unofficial Oblivion patches, I got Oblivion Script Extender, Oblivion Mod Manager, the Unofficial Oblivion patches for Oblivion and Shivering Isles, and Oblivion XP. I got Oblivion XP just because the leveling system doesn't really fit me here. Anyways, when I played, the game would constantly crash. I found no solution for it. I turned off all the mods, and even then it would crash. If I was lucky enough to get farther into the cave/early levels, the weirdest thing of all would happen. My game would go 2x the speed. Lock picking was too hard. I was at the same speed as I was running in a normal game when I was walking. I reinstalled Oblivion (+ goty disc 2) with no mods and no crashes, but the same thing happened. The game would ramp up in speed. All the sounds were the same and such, but I would be moving a lot faster than normal and everything. I really need some help here.

The only idea I have here is to install Oblivion without the goty disc that installs Shivering Isles and Knights of the Nine.

I also have other games on this computer, all working fine.

Thanks.

Sorry for the doublepost, I guess, but I really would appreciate if someone could shed some light on this.

After all of this, I uninstalled Oblivion, deleted the documents file for it (containing Oblivion.ini and save files and everything), then reinstalled. I changed the graphic quality to High instead of ultra too. Also, I installed the goty disc again. I played for a second, the game sped up, then two seconds later, it crashed. What the hell? This is getting on my nerves.
