Turn off problem

I need urgent help... So a few months ago, i had the same exact issue, where my gl553vd suddenly turns off completely (no "shutting down computer" sign, no "low battery" sign, no nothing) except for a subtle click, similar to the one you hear whenever you are plugging earphones... I had someone...

My Acer E5-571P laptop's led keep turn on after shutting down the pc. last time i faced the problem i find solution in a forum that it caused to updating to new driver , but this time i can't find the forum and can't find which drive it was?
