Windows 10: Laptop won't turn on after it's says "Restarting the Program"

Greetings,I was using my laptop and suddenly it says something like restarting the program and it turned off... And then when I try to restart the laptop it won't turn on... Power switch signal shows power but there is no output in laptop screen...I also tried to go to bios but I can't as it doesn't show anything at all in laptop screen....One thing is to note that even capslock or numlock key doesn't show power I mean to say that, the led which shows capslock/numlock is on or off... I can only change intensity of Backlit keyboard light with fn+space.I have tried to put as much as details

Asus Transformer t100ta won´t turn on Win10

Yesterday was reading on it. All of a sudden turned off and now it won´t turn on

 

Laptop won' t shutdown (or restart) and sleep [takes forever]

The situation:

• When shutting down, the laptop proceeds as normal until the screen turns off.
• After the screen turns off, it takes a while for the battery LED to go off.
• After that the power led remains on and it looks like the laptop is stuck in this state forever.
• When I try to get my laptop to sleep, something similar happens; the power led remains on, the battery led turns off and the laptop appears to be stuck in this state.

My laptop is: Asus FX553VD.

What I've tried:

• I have tried to troubleshoot power management and power options.
• Tried clean boot.
• Updated the BIOS.
• Reinstalled windows and tried shutdown and sleep (without installing the drivers and stuff), however that didn't work either.

Additional Info:

• I have multiple operating systems installed in my laptop, however this problem persists on windows only (the OSes are installed on different drives).
• The disk usage is abnormally high.
• There are spikes in CPU usage that kick up the fan really fast while idle.

Please suggest other ideas as to what I should do?

[It appears that the only option I have left is to reinstall everything]

 

Windows defender is turned off and won`t turn back on

Windows defender on windows 10 enterprise won`t turn on. This happened shortly after i updated it; when I try to turn it on it says:

This app has been turned off and it isn't monitoring your computer.

And right underneath it, it says:

If you are using another app for malicious and unwanted software use Security and Maintenance to check that app`s status.

Need for a response ASAP, thanks
