I need to push the power button again, system is starting in the regular way, and is stable in win10.

	Dear Chipette, Greetings, this is ASRock TSD. There are some suggestions for verifying: 1. Please refer to the user manual to clear CMOS. (Page 27) http://asrock.pc.cdn.bitgravity.com/Manual/AB350M%20Pro4.pdf 2. Please make sure the PCIe device power on is set to disable. Path: Advanced > ACPI Configuration. 3. Please only install CPU, RAM, and VGA card to boot; remove USB or SATA devices. Then check if this symptom relates to specific device. Thanks! All the best, ASRock TSD
