I tested many games sometimes it loads but suddenly the game stops and give the black screen again or even reset the console.

What if you run the Speed Test application?

It seems to me it's a problem concerning the HDD mod, or maybe with the HDD itself. Have already tried to check it for bad sectors errors?

The DMA implementation isn't fully compatible with all games yet.
