Achievements Gone...
I have an issue when playing ME3, my PC locks and I have to use the power button to reboot - I suspect it is a video card issue. That can be annoying but tolerable. It happens a 3 or 4 times a week...

It happen to me as well until i finish the game, then the achievements togheter whit the bonus appear. I suggest for you import your m3 character in a new game and you have the achievements( it work on me).
If you didn't finish the game i doubt you will have them
I gave that a shot... unfortunately, it didn't work (and I did finish the game).
I managed to get a few of the bonus powers back. I usually keep only 1 or 2 saves on any play through, but my first play through on ME 3 I had about 15 or so saves throughout the game. I managed to go back to different points in the game, initiate the conversation that unlocks the power, and then I had them back.
Now I keep backing up a file called "Local Profile" (I think that's what it is called) in the ME3 / Saved Games folder. If my game "blows up" on me again, I'll see if that file helps keep my history intact.
