Windows 10: My PC suddenly blocked itself turning off, and I can't turn it on again

About a week and a half ago I got my notebook repaired after backups were accidentally deleted. It also got its operating system updated to Windows 10, since originally it had Windows 7 but some years after buying it, it had problems with build 7600/7601 'this copy of Windows is not genuine'. Also, the technician said that the hard disk and the battery must be changed I don't remember exactly why, but I think because of the age, since the notebook it's 10 years old, but he also said that the hard disk could go on functioning for at least another year. Anyway, this is not the main problem, I'm just giving some context if it can help to find a fitting solution.


During this week and a half, my notebook functioned perfectly, like new, and without any problem. Anyway, yesterday I was using it normally while suddenly appeared 'Locking...' on the screen and then almost immediately it turned off. All the LED's or status indicators turned off also, and although this sounds obvious, I remark this because I was charging it while using it. I tried to turn it on again but nothing happened, it didn't turn on, except that the power indicator LED started blinking in orange, exactly five times, and it did so after each time I pressed the power button. This sudden 'lock' happened while I was playing a videogame, which was installed a few days ago from a rar file from MediaFire, but Windows Defender didn't find any problem so I though that everything was OK with it, and the game hasn't shown any problems except for 2 or 3 crashes to desktop, not a big deal. I'm still very confused because I don't know why this happened, not knowing if it happened because of a hidden trojan or another virus in this game, because of an operating system crash, a hard disk crash, a problem with the battery or maybe due to another problem.


I don't know what to do, so please, somebody help me...

PC suddenly turning off

nah, it's not that, there are no crash reports at all... The pc just turns off suddenly with no blue screen nor anything else, it just restarts point blank *Frown

 

Turn On Windows Defender Block Suspicious Behaviors in Windows 10  

The DWORD is set to 0 and I cannot get the process you suggested in the "NOTE" portion of the tutorial to work. Two attached screen shoots will show the before and after attempts to change the Permissions necessary for access to the DWORD change.




Access is denied. (Note-Protected folder in Defender is turned off)

 

Pc problem, randomly doesn't turn on sometimes.

I turned it off i'll report back if problem still persists. Do you guys have any other ideas as well, just in case this doesn't work..
