Is this an external or internal HDD? How is it being connected to PC?

May be it's related to hardware, check with another harddisk. If same thing happens it may be SMPS(power unit) 90% chance or the motherboard 10% chance. See whether you have a minimum of stable 450W.

Windows 8.1 Pro RTM x64

When you start the computer, press F2 or Del (if the screen shows a different prompt key, press that instead) to enter the BIOS (see your motherboard manual for details). Is the drive showing there?
