Hey guys! So for the past week or two I've been having my PC randomly freeze for 1 or 2 seconds it gets slightly worse as today for the first time it froze while I was playing Rainbow six siege until the game crashed.
My specs are : i7-6700k, GTX 1070 MSI Gaming X, MSI Z170A Krait Gaming, 8 GB Hyperx Fury black 2133 mhz, EVGA 750 BQ and most importantly Seagate Barracuda 1 TB HDD
Why I'm suspecting the HDD to be the cause is because I've been checking task manager alot and it's almost always at 100% disk usage regardless of what i'm doing:
Be it:
nothing at all > http://i.imgur.com/RjCJ741.jpg
or Gaming on Ultra graphics > http://i.imgur.com/fUi8eFj.jpg

This is how my Crystal disk info looks ( I've set the raw values display to 10[dec]) > http://i.imgur.com/X2Jx8Lw.png

Please help I've only had this build for about 6 months and this is the second time I have a severe issue with it. Thanks! (I'd like to add that this started about the same time I updated my nvidia drivers so could be it but the 100% disk makes me think otherwise)

Start+R, type "resmon.exe" and hit enter, go to "Disk" tab and see which process is using most of the disk active time.

It can be the system using pagefile during gaming, it can be windows update, it can be anything.

If you need a quick solution each time this happens, right click on the process and click "Suspend Process" unless it's system or your game or something important.

EDIT: For an even accurate result, below the "Processes with Disk Activity" area, there is another one which says "Disk Activity" and it shows which process is reading exactly which file (file path) at what disk speed.

Click "Total (B/Sec)" when this problem occours and it'll show the exact file to which data is being read/written to at the highest speed.

Ok well since you say the HDD is fine what do you suggest I do cause besides freezing the thing has grown generally slower and even like for example loading music file details (List view windows explorer) takes like 3 seconds, sometimes I get a frame drop for a few seconds on video games, I can relate that this MAY have started when I installed the latest nvidia drivers, should I attempt a DDU or not?
The CPU was faulty when I first built and amazon replaced it so I doubt it to be the case.
I've went ahead and ran userbenchmarks here are my results: http://www.userbenchmark.com/UserRun/3496790
Thanks alot!!

If you're using an HDD, you need to defrag it. Download Piriform Defraggler and scan the OS drive, manually click "defrag" on each file having highest no. of fragments. This'll help speed it up alot. You can also try disable pagefile on your OS drive.

A superfast way to defrag your HDD:
get a spare HDD borrowed which has some good free space, move all non-system files from main drive to the borrowed drive, use defraggler to defrag the drive which will be fast and better as there's alot more space now, then after the defrag is done, move the files back.

I also had severe issues with too much fragmentation over years with my HDD.
