Okay, I think I've been too hasty to conclude it fixed the problem because after 3 runs, it broke again. I think I will test again whether the replacement MOSFET is defective or not. If it isn't, I think I will try to replace the microcontroller with the new one. Do you have any suggestion what I can try to fix it before I replace the micro?

Considering that you can get a new off brand microcontroller ramps and drivers for about 34 bucks off ebay I would just go replace the whole shooting match.

I really think the issue is power or the power supply wiring, not the mosfet or the microcontroller. In particular, check the negative wire between the PSU and the Melzi is secure at both ends, and check the soldering of that connector on the Melzi. If you have a bad connection there, it will try to draw the ground current via the USB port, which may cause the symptom you describe.
