PC hangs at random times

[Reneul]

Hello,

I have a peculiar issue with my PC:

At random times, it just hangs (mouse pointer still works, but everything else is unresponsive).
If I reboot the pc I get the "Reboot and Select proper Boot device" error and can't see the hdd in BIOS. If i shut-down the PC and turn it on, then the hdd is recognized and everything works until the random issue appears again.

System specs :
Motherboard : Gigabyte H77-DS3H
CPU : Intel CoreTM i7 3770 IvyBridge
HDD : Western Digital Blue, 1TB, 64MB, 7200rpm, SATA 3
Power source : Inter-Tech Energon 650W
RAM : Kingston 8GB 1333MHz DDR3 Non-ECC CL9 DIMM
OS: Windows 8.1

I also want to mention I have this issue for 1 week, and the PC is 1 year old
At first tried to reinstal my OS, but after that the issue resurfaced. I guess it's most likely a hardware issue, and I want to know for certain what to send to warranty (not all parts are from the same place)

Any help would be appreciated!
Thanks in advance.
