PC Restarts Randomly Every Day

[lorddark94]

Hello, my PC restarts everyday without any reason, it boots up normally and works without any problem. I've checked if it was a hardware issue but I'm pretty sure it isn't. Today it restarted 5 minutes later after first boot. This is an issue that I've had for a few months now and it has started getting annoying because it happens randomly when I'm watching videos, doing work or playing video games.
Here are my Specs if it helps:
Motherboard: ASUS M5A78L-M PLUS/USB3
CPU: AMD FX 6300
GPU: GeForce GTX 750ti
RAM: 2 x 4GB HyperX Fury DDR3 1866MHZ
COOLER: HYPER X 212
HDD: WDC WD3200AAKS-75L9A0

Disconnect and reconnect ALL connections from your power suppily (including the one that goes to your wall outlet). Also, if that doesn't work, try connecting your PC to a different wall outlet.

When your PC restarts, does it just go black then restart (basically a hard reset), or does it gracefully restart?

It is a hard reset
