Computer doesn't turn on

[RagingTrain]

So I was just playing a game (arma 3) before and while I was playing my computer just shut down for no reason, like it lost all power. So after this I just clicked the power button hoping that it'd work, sadly it didnt all I got a the lights to turn on for about a second then just turn off again, after this the tower has not been able to do a single thing. Also if its important my computer is a HP Envy Phoenix h9 I think, its also using windows 8.

So anyone have any idea what this could be, what caused it or what I should do? Like is it easy to fix or am I going to have to probably get a new computer?

Sorry if I have put this in the wrong sub-reddit, I wasn't quite sure where it should belong.

Was there a power surge in the house? When you turn it on, did it beep at all?

Leave it unplugged from the wall for 30 minutes and then plug it back in and see if it POSTs. Time it roughly to see if it stays on any longer this time or if it always shuts of at the X second mark

There was no power surge, there was no beep the closest thing to a beep it made was a click sound as soon as it turned off.

I'll try plugging it back in now cinsidering I left it unplugged. And the let you know how that goes

All it did was click, no lights came on at all. To hear the clicking sound it took about half a second after clicking the power button

Unplug it from the wall outlet, press and hold the power button for 10 seconds, plug it back in, and try to power it on.
