I’m with catloaf. Consistent CPU soft locks point to a possible bad memory module or CPU.

Clear CMOS.

Try removing one memory module at a time.

See if there is an option to disable hyperthreading in bios.

Another thing to try is to remove the CPU, careful not to damage the LGA pins on the motherboard, and clean the CPU contacts with alcohol. Take care to ground yourself out and the case before handling the CPU out of socket.
