Laptop shutdown by itself in boot

[Alexander13]

This is my problem: https://youtu.be/IMgrGogcBno
I uploaded on yt because i dont' know how to explain this.
I already checked the ram, cpu, gpu and hdd.
It's not a constant problem. Sometimes i can log in and do my thing without any problems(the temperature and the frequency of the cpu is normal) , i can put in the sleepmode and everything is okay if i want to open it again.But if i click shutdown, the problem appears again when i press the power button to start. The problem persist even with/without the battery in and the power cable plugged in.
The bios is updated and i tried everything(cmos reset, hdd replacement, reinstall windows). I tried the stress test and a gpu benchmark and everything was fine.
Thanks and sorry for my bad english.

Today i found something interesting. If i change something in bios (like secure boot or something else), the shutdown problem disappears. I tested this a few more times. It's not a coincidence. Conclusion: if i want to boot properly, first thing to do after pushing the power button is to enter in bios and change somethig like secure boot(enabled or disabled, it dosen't matter) and from there i can log in and everything runs okay. I can record this and upload it if it helps.
Yes, i replaced the original hdd with a 120 gb ssd hyperx because the old sshd had some problems(failed in hdd test). But i don't think the hdd was the problem because the problem is still there when the hdd is unplugged.
I think the bios is corrupt or something like that. Today i tried a bios restore with a recovery usb flash drive. I followed the steps and everything and it's shutting down exactly when the recovery screen shows up. I can't even update it to the latest version(i have version f68 from 22 jul 2016 and the latest is f68 rev. a from jul 26 2016). I think that the problem is the bios chip.
Thank you!

The problem appeard after i shutdown the laptop by pressing power button for a few seconds. I've done that because i was stuck in windows login screen( no password box or user picture, just the background and the turnoff sign in the corner). I didn't saw any update notification.
