Hi all,

I suppose my problem is related to my SSD so I post there but not sure actually.

TL;DR : Total freezes happened in games, reset the PC at each time, one time it didn't start back and have an "unmountable boot volume" type message. Reinstalled Windows and it redid it one time. Second reinstallation worked and no freeze for now or blue screen BUT it is super slow (like as slow as my 4 years old shitty laptop)


So I built my computer like 6 months ago (first build), worked fine without major problem until now. I actually did have a problem with my GPU but it is fixed and was a pretty dumb thing (alimentation cable not were a little disconnected because the case was pressing against it) and it's probably not related.

So some time ago (like 2 weeks), the PC starts to have random freezes (I couldn't do anything else and a "continuous strident noise" comes out of the speakers). It was always in games. My only solution was to reboot the computer (by pressing the power button). It happened a few times, not that much like 4-5 times. Then, the other day, it happened again so I do the reboot like usual but when I restart it display a blue screen with "Unmountable boot volume" (or something like that). I should precise I use Windows 10 and have the OS installed on my Sandisk SSD (bought with the PC so not an old one) which I do believe may be the problem (but I don't know much about these things).

So, I searched solutions on Internet and tried all the command prompt they said (chkdsk, fixboot, ...) with a Windows 10 setup tool on a USB. That didn't have any effect on the problem sadly. I also didn't have any restore point or system image available. So I try the last thing remaining, reinstall the OS. I did it and it seemed to work fine enough. Except it was super slow and did the same problem again after like a few hours (unmountable boot volume screen). So I reinstalled Windows without keeping files this time (I made the necessary backups in the meantime).

It worked fine and didn't redo the freeze effect or the blue screen unavailable boot volume yet so good news ? Except, it is still super slow (like shitty HDD slow, not SSD or even normal HDD, it takes like 5 minutes to load completely Overwatch for example whereas it was almost immediate before the problem or takes 30 seconds to open the start menu on an almost empty OS drive) and some stuff just doesn't work (well maybe by waiting more). I suppose it is also linked (and not an Internet problem) but lags, buffering problems, web pages taking too much time to load also happens all the time (I took a noticeable 15-20 seconds to just open this submit page). And sometimes (few times though), it works well like before.

My supposition is it comes from the SSD as the OS is installed there and I believe all freezing games were on the SSD. i'm not sure but I mainly remember it happening in Overwatch which I played a lot during that time and which is on the SSD. It also takes more time to browse the SSD than the HDD in the explorer (when the explorer even works in a timely manner).

I did a Crystalmark test and didn't have any problems during it though as far as I know. If it was a defec with the SSD, why would it have worked during months so it appeared over time but considering the drive is like 6 months old it seems weird (I ask that to know if that would be warranty covered).

Also, I did read on SSD advice though and saw that they are limited in number of writes (though it should be a very high number) and that temp files shouldn't be on the SSD and they were (since the browser was there and it is the main temp files sources). I also am a big user of hibernate instead of shutting down the PC (I like having my browsing session available right away and did it by habit from my old PC that took 5-10 minutes to fully start) which you shouldn't do with a SSD apparently.

What should I do to determine the problem and to fix it ? If it is the SSD failing, is that covered by warranty ?

Could try a different sata cable, it could be that simple

An unmountable boot volume error means that the operating system cannot boot from the hard drive either because the boot files are corrupted, the hard drive is faulty or there is a problem with the cable connecting the hard drive to the computer.

try running this on ssd: http://www.techspot.com/downloads/6014-as-ssd-benchmark.html

this was my scores recently as comparison

Do you have latest BIOS and motherboard drivers?

Tried it and it didn't change anything sadly.




Ok yeah there is definitively a problem there, I can't even finish the test. Well actually, it often starts quite well with green scores comparable to yours but at one step (not always the same, though often the second one, 4K), it slows down so much that it basically stops or takes a lot of time to finish. Which is quite consistent with the fact that sometimes it works well and then lags A LOT.



How do we check that ? It's not in the peripheral manager. Isn't it automatically updated ?

Thanks but there's nothing to run with this I think. It says SMART is not taken in charge actually. I will contact them and see what they say.

Yes, I noticed after i linked their tools that its really only for firmware updates. If you had a Samsung drive, their software at least includes benchmarks so you can see how your SSD is reacting to certain requests.

GL with Sandisk.
