My Laptop Will Not Boot

The other day my laptop Asus Q550LF would not boot. First night after I got from work, it did boot for a few minutes then shut down. I waited for a minute or so then turned it back on and it worked just fine without any incident for that night. The next day after work, I tried to put it on and t won’t boot at all. Upon pressing the power button, the front lights turn on, I hear the hard drive click a few times then all the lights turn off on the front, and laptop stops everything. This whole process takes about 3 seconds from the power button push to the crash and the screen doesn’t power at any point. My hard drive is good but I suspect the motherboard might be at fault although I would like to be sure about it before buying another one. I would be happy to hear your advice, thank you for your time.
