I don't know what your problem is, but I can tell you that the problem is not because your laptop cannot play Mass Effect at all. I have the same video card as you do, along with a weaker processor (an i3 instead of an i5), and my laptop can play it quite fine at high details and textures- the frame rate hovers at 30 FPS, which some might find unacceptable, but it works for me. You can dial down the details and textures to get better performance. Either way, it is certainly playable on your laptop.
My advice is to try uninstalling and reinstalling the game. Beyond that I can't help you.
And Gorath, no, the Mobility 5470 is not a laptop counterpart to the desktop 5570, if that's what you are suggesting. The 5470 only has 80 stream processors and a 64 bit memory bus width, compared to the 5570's 400 stream processors and 128 bit memory bus width. The closest laptop counterpart to the 5570 is probably the Mobility 5770, which has the same amount of stream processors, memory bus width, and clock speed (650 MHz). The Mobility 5470 is simply a Mobility 5450 with a higher clock speed, which is in turn the laptop counterpart of the desktop 5450.
