Here is my system: https://pcpartpicker.com/list/z29kRk

Ive had it in this configuration for about 1.5 years now,, I do have the i7 OC to 4.8 Ghz at 1.285v and with the AIO it never goes above 60*C. I was playing some games when it suddenly froze and turned itself off. I tried to turn it on manually but nothing comes up on my monitor and it power cycles itself.

Did my computer actually die or what could it be?
