Pc not booting up all of a sudden

[DaBird]

Hi
I bought a new graphics card as my old one 980 wasn't working properly and pc was blue screening sometimes I bought a 970 and it's been running like a dream.. however
I was gaming and listening to a TV programme the pc froze randomly and now I get this when trying to boot up

Pri master hard disk:s.m.a.r.t. command failed?

Pri master capable but command failed
Pri slave capable and status ok

Press f1 to resume and it just isn't booting up ?

Not sure how to post pic as I'm on my phone

Any advice would be massively appreciated
