Pc randomly shutting odd

[samthomas]

This has happened 3 times in the 10 days since I built my Pc, and only whilst gaming. 

 

I can be playing for an hour or so and sometimes it doesn't happen, but when it does everything goes black and switches off, no warning. The most recent time when rebooting I was presented with a repairing C drive message.

 

As far as I'm aware my temps have been fine. Can anyone think of a reason this may be happening? I've read maybe faulty psu but this most recent one with C drive repair made me think it may be a drive issue? 

 

I just don't know and I've spent a good bit of money on these components. Any help would be greatly appreciated.

it'll repair on unexpected shutdowns regardless of why it was unexpected

does the computer have ram or was that not needed?

OK, it just didn't do that repair on previous shut downs. Sorry, ram is vengeance 3200mhx 16gb

well if it's more than one stick then pop all but one stick out and see if that stabilizes it
