Better to start from the beginning .

1- Is there any liquid spill or corrosion observed.
2- With diode mode test all coils sarching for short and post all the results.
3- Post your old dump .
4 -PQ 302/303 Drain , source and gate voltages.
5- U28 basic requirements

is it normal that the board will start but it vey hot? from the heatsink, maybe beacause my board is turning off bcause of the heat?

Have you tried the bios program. You can check for short circuit on USB data pins. There are not many options other than audio and ethernet chips. the processor may be problematic.
