Yes, I confirme dawn today (2 AM). The problem is graphics card ASUS, because remove ASUS and change BIOS for onbaord VGA. It´s OK. At moment not problem.
If it freezes on the BIOS setting screen there's a problem with the motherboard. If it's freezing during POST (power on self test), there could be an issue with any device necessary to boot the system (graphics, cpu, memory, motherboard, harddrive, etc)
