My 1 year old self built computer have been having the same problems for months with me trying different approaches to trying to repair my computer

Problem

1. The problem is that the computer shuts down RANDOMLY. Pretty much whenever it feels like it.

2. When trying to turn it back on the PC will turn on, everything lights up, fans turn on but no beep and nothing will show up on the screen. The computer will then turn itself off and on with the same results and nothing on the screen

Therefore I would have to manually turn it on and off until it works again (it sometimes takes a lot of tries and sometimes very few)

What I have done

CPU - Stress test it with prime95 getting BSOD but found out on the internet its a driver problem so I do not believe that is the problem because its the first time I've ever gotten BSOD. (1 problem at a time)

GPU - Stress test results OKAY!

RAM - Memtest results OKAY!

Drivers - updated all drivers (e.g Chipset, BIOS, etc)

I've also taken all the hardware out, rewired and reseated all the chips

Cleaned out the dust

My Specs

Motherboard - ASUS P9X79

CPU - Intel Core i8 - 3820 @ 3.60GHz

GPU - Gigabyte GTX670 2 GB DDR 5

RAM - Kingston 4GB x 4

PSU - ANTEC 620W

Please try helping me out guys!
I've been trying to fix it for months
 
Solution
Had this in the pass... could be a dying Power Supply or your Mobo dying.

In your description, I would suspect the Power Supply at 80%. Had the same problem with an Antec Power supply.

even though the PSU has only been a year old?
 


Mine was brand new... so yes. Try to find an old Power supply to isolate the fault and do a RMA. I stay away from Antec since that incident.
