PC Freezes with 100% Disk

[Kinohki]

So first off, I don't post often and haven't in a really long time. Sorry if there are multiple threads of this but I'm at my wits end trying to find a current fix that works.

My PC is running windows 10 Anniversary patch (1607 build 14393.222) and is running a Mushkin Eco2 512 gb SSD
AMD FX4100 3.6 ghz quadcore
8gb 1866mhz ram, I believe it's corsair. Can't remember off the top of my head
600 watt power supply
and a Geforfce GTX 970 graphics card.

What's happening is my PC randomly will lock up and become entirely unresponsive. This is limited to the 1607 anniversary patch because before hand it was not freezing at all. My rollback period has expired and, in all honesty, I really don't want to have to reinstall if it's not necessary. At first I thought it was the CPU bottoming at 100% but it t urns out it's the disk. I have a single SSD, the OS and everything is of course stored on it, so no multiple HD's here.

I have tried turning off windows notifications, disabling superfetch, I run my PC on high performance power options so the AHCI link state power management shouldn't be an issue either. I have the majority of my services disabled upon startup so that is not an issue as well, in fact my OS runs as lean as I can possibly make it. That being said, I'm at my wits end trying to resolve this issue and have tried everything short of a refresh or a complete system restore.

I have also checked the event viewer and there are no errors other than a random distributive com which I'm pretty sure isn't related in any capacity, though I might be wrong. Occasionally, very rarely mind you, my PC will restart itself and has done this a few times, those are the only errors in my event log. If anyone has any other ideas, please share them as I'm getting quite annoyed. I can't game at all because my PC just wants to randomly freeze and even generic use like checking news has become annoying. Thanks in advance and sorry for the long thread.

Edit: Forgot to mention that SFC finds no integrity violations.

Hey there, Kinohki.

Did this problem began right after you got the anniversary update, or were you able to use your computer normally for awhile? I'm asking because it might be coincidental if it didn't start occurring at about the same time.
First and foremost you should backup your most valuable data (id you don't keep regular backups), just to be on the safe side.
After that I'd recommend that you try the SSD with a different SATA port and different SATA cables, to see if the problem still persists. You should also check for firmware updates for that SSD model and install it if you find one. Downloading an SSD diagnostic tool and running the tests, to see if anything alarming pops-up, might be a good idea as well.
This type of issue could also be caused by faulty RAM, so you could run a memory test as well.

If it turns out to be an OS update problem, it might be best if you turn to Microsoft's customer support for assistance. There might be fix for it or some other workaround, which could prove useful.

Hope that helps.

Hey Boogieman, thanks for the tips.

It started right off the bat with the anniversary. I figured it'd be patched away shortly since I saw a lot of people complaining about it and it was a pretty serious issue but I guess I was wrong. I haven't tried using different sata ports...That sounds like an idea to try. Will definitely give it some more attention when i get home from work.

Do you know of any good, reliable SSD diag tools? I'm not really familiar with any myself.

It really sounds like it could be the update then, but it wouldn't hurt to check it out, just to be completely sure. I always recommend that you go for the manufacturer's diagnostic tool (unless it doesn't offer such a tool, or you want to double-check with a 3rd party one). Most 3rd party HDD tools should be OK for SSDs as well. Unfortunately I can't recommend a specific one, because as an official WD rep, I can't suggest any products/devices, which are not under the Western Digital brand. However, you can pick one (or more) from this article: http://pcsupport.about.com/od/toolsofthetrade/tp/tophddiag.htm (it has both brand specific and 3rd party diagnostic tools).
