Restore Leopard to original specs

[Canerican]

I was wondering if there was a way to basically restore Leopard to the original settings without losing my files. In other words all the setting and preferences would go back to factory defaults, cache would be erased, and the applications not included would be erased. My MP3, MP4, and DOC files would stay but everything else would be gone.

Well removing the apps is probably easiest to do manually. Resetting preferences mostly just involves trashing your preferences folder in your library.

The thing is that I want to fully remove apps bundles, receipts, everything. I am having a problem with Leopard, and I think that it might have been a setting I put in to affect Alpha values on Leopard, since I don't remember which programs I have used that still might be affecting me, I just want to trash it all.

EDIT: tried deleting the Preference folder, and I got the warning below.

Whoops, I mean to just put everything in the preferences in the trash. Restart, then you can do whatever.

Well I ended up doing an erase and install, stuff is mostly better.
