Did you had ME installed over Origin before?
If yes, did you uninstalled the Origin copy before you installed with Steam?
If you move the save games out of the "...Documents\BioWare\Mass Effect" folder, is the game starting normally?
"Did you had ME installed over Origin before? If yes, did you uninstalled the Origin copy before you installed with Steam?" No.
"If you move the save games out of the "...Documents\BioWare\Mass Effect" folder, is the game starting normally?" Yes. So long as there's a "Save" folder present, the game runs normally.

Try to run Origin and if that doesn't help, the game as Administrator. (Right click the Origin shortcut on the desktop > Run as an Administrator.)
If that don't helps preform a clean boot, disable your virus scanner (Do it in offline mode if you have concerns.) and test the Game in clean boot mode.
@holger1405 Thanks for the advice.
I ended up getting so annoyed at ME, that I uninstalled before I received your reply.
I've reinstalled it via Steam and manually added it to my Origin launcher using its CD key. This also deleted all my save games.
The game now seems to be running properly, if I disable UAC and Windows' anti-virus utility, have Origin running, and start the game by running masseffectlauncher.exe as an administrator – not by starting it via Steam.
UPDATE: I posted too soon. I just tried to play Mass Effect, and it froze while loading my last save game. Same issue as before.
I did try your suggestions, including a clean boot, but the problem remains.

@richard_cosgrove; Don't play through Steam. Try direct from Origin.
