BF4 Completly crashing my PC (manual re-boot) [ Edited ]

[Whopperlele]

i have just built my first pc,

SPECS-

AMD FX 6300

Asus M5A97 R2.0

Gigabyte R9 280x Windforce

8 Gb corsair vengence ram

Kingston HYPER-X 120gb SSD

WD 1 TB black HDD

ANTEC 620 watt PSU

I start up the game and it will allow me to play for about 5 - 10 minutes before my completly crashes once i re-boot this usually dosent happen again.

i have played other games like Minecraft for hours on end without this happening, and surfed the web. The only time it crashes is when i am playing BF4 ihave check my temp levels and they all are fine.

Can anyone help me??
