Asus Laptop Restart when loading YouTube !

[shamaltech]

I have an Asus X510UN laptop.
It has a weird problem that it restart everytime while I'm loading the YouTube.
This happens only when the laptop plugged into charger.
When using battery power,it works fine and YouTube works without restarting.
Tried with Installing new Windows,changing SSD and also Flashing the BIOS.

Any help?

I guess it depends on what you are watching??
