When I start up Oblivion, it gets to the main menus and everything fine, but when I try to load a game it crashes to the desktop, and when I try to start a new game it doesn't do anything!

I think Oblivion stores saves and configuration info in My Documents somewhere. Find it, then move all those files/folders elsewhere temporarily and try starting the game (with a clean config)

If chefkw's tip doesn't work you could have corrupted files somewhere.

I've had similar problems to this myself, do you use Oblivion Script Extender, if so try reinstalling or updateing that.

If you use that many mods it's a good idea to use Oblivion Mod manager and FCOMHelper if you don't already.

I've got ovewr 100 mods running on mine but it does take some experience and experimention to get the load order working

I just hope you won't have to reinstall everything.

I tried moving my files, and it still won't start a new game. Also, I do use Script Extender and Mod Manager. I could just try reinstalling and saving all of my esp files, and try putting them in one by one.

So, did this suddenly happen after working ok or did you change anything, add new mods etc.

One thing that caused a crash like this for me was a GUI mod that changed the fonts and I forgot to update the oblivion.ini, it crashes out as soon as it tries to load the fonts.

Have you tried using FCOMHelper to arrange the load order, I found that quite useful. Also look into Wyre bash, that can help spot incompatible mods.

If all else fails then you do need to reinstall and add mods systematically. Pain in the arse I know, but once they are all in and working RAR or Zip the oblivion folder, then if anything goes wrong you can just replace the whole folder.

I don't use all the mods you do so couldn't tell you off hand of any blatant clashes.

Hope you get it sorted soon as it's an awesome game
