Dragon Age Origins won't load and crashes

Hi,

I installed DA Origins on my computer yesterday and it worked fine, crashed about 2-3 times in the space of 5 hours but still it worked. Today on the other hand I go to my computer boot up DA Origins and it keeps crashing on the loading screen, I literally press load game, pick my character and it immediately crashes and sends me back to the desktop. 

I do have mods on it but it worked fine yesterday when I downloaded them so I don't think the mods are the problem. I did turn off my computer without shutting down DA Origins yesterday and there was a windows update today so those are really the only problems I can think of which is making it not work.

Any feedback or support would be much appreciated.
