If you explain your installation in detail, perhaps somebody can help. That means, the amount of RAM you have, your video card, your CPU. For starters.
I'm moving this to Tech Support, in any case, but leaving a redirect, just in case somebody might be able to help in the Oblivion forum.
In the future, please consider titling your thread with something that bears a resemblance to its contents, too. Might draw in more readers, that way.
