Always a good idea would be - sfc /scannow
Though seems hardware issue.

Sounds indeed like hard-drive. 
 
Failing hard drives can cause strange issues, also on other hard drives in the same system. 
 
Also as much people like crystal disk,  it can be unreliable or at least difficult to read... i had 2 malfunctioning hard drives and crystal disk said "good" and i didn't see any abnormal errors or such either. 
 
Lastly there are no critical errors in your event log, so it doesn't look like something "serious" per say.  (Could still be hard drive of course)

check crystaldiskinfo for your mechanical drives, and look at "read error rate", "write error rate", and "seek error rate" parameters.
 
if one of those is extremely high (let's say 5 digits) then the drive has severe mechanical issues, and is probably causing the hangs. crystaldiskinfo doesnt take these into account when assesing a drive's health, so even when this is going on to the extremes, it'll still report as healthy. (i have a few drives that have rates up in the millions, and still say they're OK, while they clearly arent)

Just checking, but are you planning on overclocking, and if so how seriously?

For the price of that air cooler, I would just grab an AIO water cooler.

What is with the forums today. Guys, the 390 is the better card, it performs better across the board than the 970, if not exactly the same, ontop of having more than double the vram. He doesn't have a g-sync monitor, and doesn't use shadow play, there's literally no reason for a 970.
 
No, the 390 and 970 are 320-350, but the 390x is $370+

I thought something was a bit off about that. I read 380  

350W MIGHT be enough, but everyone will advise a 500W or more PSU, ideally from tiers 1 to 4 on this list:
 
 

Lol, here is the list:

They do. If you really want to check here are the sizes of both of those cases and the height of the coolers:
 
Thermaltake - 484.0 x 202.0 x 426.0 mm
Antec - 475.0 x 205.0 x 457 mm
 
Be quiet! - 160mm
Noctua - 165mm
 
Should be fine

You could probably find a Justin Bieber fan pretty cheap.

Should be more worried about that stock cooler

Your rhyming hurts my timing.

I haven't been able to find it... Not even on MSI's website.
 

And 3 answers in 10 seconds... better than zotac customer service i think

I was planning to get one of those keyboards suggested, but then i saw the Corsair RGB backlit keyboard. Drool.....
