Big problem with SSD! Files dissapearing!

Hello everyone!

I am writing to ask for advice for my main SSD, I hope that you can help me

The thing is that it’s the second time that it has happened to me (the first was last Friday)
Here it goes:

I work with my MSI-GS60 2PC at my office of architecture, and I use Autocad, Photoshop, etc. Well, last Friday I decided to delete temporary files with CCleaner since Photoshop warned me that “the virtual memory disks are full" = I had only 300mb on my C: SSD M.2 disk (I also have a secondary SSD M.2).

I closed Autocad, and Important: I think I left Photoshop opened, and did the cleaning (I detected 5gb of temporary files, most of Chrome), and just after finishing, the application closed and Surprise! the folder and all the files which I was working previously disappeared , as well as the own folder of the CCleaner portable, another folder with work files and other files from the desktop that I had last opened a few days ago... imagine my face. I checked for hidden files (they were already visible), recycle bin, etc. Nothing. I tried opening the files with the programs and they did not find them.

Finally, I did a deep analysis with Recuva, and located them in " C: /? " ... then I "recovered" some files to my other SSD, but when I tried to open them with the programs it said that they were not valid… so in the end, I gave up and assumed the lost files.



The problem is that it has just happened to me again . I was retouching a photo with Photoshop (again), and when I closed the program saving the changes, the same thing: the photos of that folder, as well as other icons and some "random" files on the desktop have dissapeared.

I do not understand anything ... what do you think it can be? The laptop and hard drive are just 2 years old, so they should still have enough useful life...

I discovered that some new "volumes" appeared on my C: [/b] disk that I did not have before (I remember I only had the main and one recovery volume with 2gb approx).



The curious thing is that both times it happened while closing a program (in the first one I believe that Photoshop was already closed when I started CCleaner, but now I doubt it), could be a way to investigate there? software problem? Or as it is affecting other files on the disk it has to be an SSD problem?

I have checked the SSD with Crystaldisk and it seems to be in good condition:




On the other hand I have done the analysis again with Recuva, and this time the deleted photos are not in "C: /?" but in the original folder inside the desktop (that if I open it is empty), and if I "recover" the photos (in “Excellent” conditions), I can’t open them because they are defective.

This time I have not lost many valuable files, but I would like to avoid it happening again because I work every day with my laptop...

What would you do? Is my main SSD defective? How can we find out the SSD problem?

I would greatly appreciate your help! Thank you very much!

 

I would forget about 'finding out the SSD problem' - junk that SSD, if that is indeed what is trashing your files.

(I'm not quite understanding what you're doing with CCleaner... but it doesn't look right either...).

Hope you have backup(s) that you have verified as being usable? Don't do a backup with the system in that state until it is rebuilt and verified working, or; you've replaced the SSD.

128GB SSD's are worse than toy/novelty USB keys... after two years in use as a system drive; time to junk them.

 

Have you tried a chkdsk or scanning the risk for file system errors? Also like @tilleroftheearth hinted, perhaps stop with the CCleaner for a little while until you can isolate the problem and make a backup of your important documents.

By the way it's hard to recover files from an SSD drive because TRIM will reset "blank" areas of the disk to '0' to prepare them for writing.

Your drive does appear to have a few bad blocks which I think is a bad sign.

 

Hello tilleroftheearth and namaiki, many thanks for your kind help!

Now I have all my files saved on my second SSD, so now i'm working just with my programs installed on the supposedly defective SSD C: with files of my second one.

The files I lost were on the desktop of my first SSD C:, so I hope that this way i'm not loosing again something (as while I fix it, I need my laptop to continue working).

I just had CCleaner as a portable version, and i've just used it 3-4 times to clean temporal files like from Chrome (so it's not running in the background). Anyhow it was already gone before the second time it happened, so it cannot be the problem...

It makes me think that during the first time maybe I left Photoshop opened on the background while doing the cleaning with CCleaner, and maybe it got corrupted? because the second time it happened while I was editing a picture in Photoshop...but it would be no reason of why also some random icons like Itunes, My PC, etc also disappeared...

I just checked the disk with chkdsk and here are the results (translated from spanish):

It said that it has corrected some system files...but no idea how important it is...do you know what does it mean? is it related to "bitmap attribute"..

I've tried after the scan to edit some pictures with Photoshop of my desktop and it went fine...but i don't understand why some random icons (like My PC or Itunes) also disappeared...as they are no bitmap

Another thing that is happening since some months, is that sometimes if I want to move an icon in the desktop to a determinate space, is like there's something hidding/blocking it, because it is placed next to it and moves other icons instead (and I have no hidden files). It still happens with some spots of the desktop...can it be related?

Any ideas of how can I check if the problem is already solved?

I really hope that it doesn't repeat again..

Many thanks again!

 

Well, it is a good thing that chkdsk was able to fix some errors. It can be caused if the computer is improperly shut down, e.g. the computer froze so you had to hold the power button for five seconds to get it to turn off. Has that happened much?

As for the icons disappearing, that could be a sign that there is/was a lot of corruption on your hard disk or maybe your RAM could be flaky? How much RAM do you have? Is your page file on or off?

Long shot.

Could you try do the chkdsk scan again and see if it picks up any more errors? Keep in mind it is possible that SSD might just be picking up bad blocks with file system corruption happening that way.

 

victorgm, you're welcome. Hope we're getting you close to a stable system again.


First; did you check each file you saved to your secondary SSD? One or more may still be corrupted (better to know now than later...).

Second; when running CHKDSK /R, you should shut down afterwards (full shutdown; wait a minute or two before starting the system up again) and then repeat with another CHKDSK /R scan. Continue this sequence until there are no more errors reported.

Third; download HWiNFO and check the health of your SSD(s). When you run the 'sensors' part of that package (I recommend the portable version, btw) scroll down to see the SSD(s). There you can check their health and total TB's written. If that is high (anything is high for a small 128GB SSD...) then it may be time to replace it.

Fourth: The best way to use CCleaner is to reboot your system first. Let it idle for 5 to 10 minutes and then clean out temp files and the like. HIGHLY recommend you do not use the Registry cleaner (a windows clean install is in order afterwards - if you want your system to operate as it's supposed to).


How much RAM does your system have? How much free space on the drives? What O/S are you running?

I would disable the pagefile (make sure you reboot twice) and also disable the hibernation file too and then run the CHKDSK /R a couple of times again. If you have more than 8GB of RAM (and depending on your workload...) you may want to leave those space hogging system files permanently 'off'. Just make sure you test with your workflows and workloads with non-critical data to be sure the pagefile isn't needed.

If you don't have any further 'fixes' by running CHKDSK /R, you may be lucky and the system is fixed for now. I hope this is the case for you.

Good luck.

 

Many thanks again namaiki and tilleroftheearth! I really appreciate your kind help!

So, I will try to summarize

- To give you more perspective: 4 months ago my secondary HDD 1TB 5400rpm was defective (lost lot of data because of head crash), so I replace it with my secondary SSD Samsung EVO. Anyhow, some programs were installed on that drive, so maybe there are missing or corrupted files because all this software was gone improperly. This could maybe be a reason for the "blocked spaces" of my desktop (or why there is a folder on my desktop that i can't simply delete or rename).

- I took the chance when I installed the new SSD M.2, and upgraded my RAM Kingston KVR16S11/8 8GB to 2x8GB (Dual Channel using the same model). I have tested the memory with the Windows Memory Diagnostic and went fine.

- My computer had frozen sometimes (like 4-5 times during this year), with no other option that shutting it down as namaiki said (but I think that it also happened before the old HDD crashed - not sure about this, maybe it was just after that)

- I've Windows 10 with automatic updates.

- My page file is on (using 3gb), and i'm confused because of the mixed comments about it on internet...as I work with high-demand RAM software (CAD and Rendering software, Indesign/Illustrator/Photoshop and some video editing...should I disable it? (although I think i've not used completely the 16GB RAM in these 3months)

- I've just disabled Hibernation file and saved 7GB, yei!

- When the first problem happened, I had just 400mb free space on C: (now I know that it's very bad for SSDs, as they should have 15% min free space, and that's why I was cleaning 5GB of Chrome temporal files with CCleaner), and the second time I had 5GB free on C:. On my second SSD Samsung EVO I have plenty space (200GB free).

- I checked the files saved into my secondary SSD, and most of them were fine (excepting the ones that I recovered with Recuva because they were gone).

- I've checked again the disk twice with CHKDSK /f (first one) and /r (second one), and no more errors were found.

- I found something interesting, as I saw on the events manager that "Intel Rapid Storage Technology" crashed on both analysis...is it normal? right now I've opened it on the Control Panel and seems to work fine...can it be related?

- I've downloaded HWiNFO and both SSDs are "fine", but we can see that the first SSD had 22.868GB of Writes and 16.414GB of Reads..is it too much? It says that it still has 67% of remaining life...



- I think that I won't use CCleaner anymore haha ...but i've to admit that sometimes (but like +6months), I did some "Registry cleaning"...auch

I guess that I should reinstall Windows from 0, so that it can have a clean start...but now i'm not sure if the Recovery partition is also gone...because you can see on the second image of the topic that the partition which is called "Partición de recuperación" is empty

What do you think guys? could maybe CHKDSK have repaired the main problem that caused the disappearing files? is it 23TB Writes too much? should I reinstall Windows and/or replace SSD? should I disable pagefile even if I work every day with high-demanding RAM software?

Many many thanks again!!

 

Have you tried to disable fast boot on bios level and in windows 10?

 

If you change the size of the icons on the desktop, do the blank spaces remain? Try click the desktop in a random spot, hold down Ctrl and scroll on your mouse/touchpad.

If the computer improperly shuts down it will often do a file system scan, but if it doesn't detect it I usually just get it to do one just in case.

That undeletable folder is a bit annoying though. Is it safe to say that you can't move it into another folder and then delete it?

Did you do file system checks on both SSD drives?

Intel RST crash is nothing to worry about. I don't think it does anything besides giving you the option to change settings.

The amount of writes on your drives isn't anything too excessive at all. But CrystalDiskInfo did report bad blocks which hopefully won't increase.

Are the following settings as default? http://www.thewindowsclub.com/enable-disable-disk-write-caching-windows-7-8
(the top one ticked, the bottom one unticked - which is what I would consider safe/typical settings)

 

Thanks for the detailed response.

With programs installed on a drive that 'died'/'disappeared' from Windows - I HIGHLY recommend a clean install of the O/S.

After running any registry cleaner on a system - I HIGHLY recommend a clean install of the O/S.

With both statements above being 'true' for you; I HIGHLY recommend a clean install.

Download the Windows 10 Installation Media Tool and also Rufus USB creator tool and use an USB key of 8GB or bigger to create an install key.

After you have created the Windows USB installer; back off all your data to an external drive (depending on how important your data is; to two or more different drives - and, a cloud location or two). Remember; a single copy of your data is not a backup...

At this point; I would junk the 67% 'healthy' 128GB SSD - or at least relegate it to more mundane and non-important purposes (a USB drive with a $5 enclosure is nice move files around with...).

At this point; I would also not be trusting your system as-is with any of my data. It is 'broken' and nothing short of a clean install will fix it. To be perfectly clear; using the built in Windows 10 'recovery' options should be avoided (unless you have time to waste doing this all 'properly' again).

Now; buy as big an SSD for your main C:\ as you can afford (I recommend 1TB SSD's in 2.5" formats, still...). Do not buy TLC 'garbage' for your workflows. Otherwise; you'll be doing this again in a few months. If you can track down an SanDisk Extreme Pro 960GB SSD; you're golden.

Free space is not the same thing as 'unallocated' capacity on an SSD. Just like short-stroking an HDD is not the same thing as free space too...

See:
http://forum.notebookreview.com/threads/why-over-provision.760922/#post-9766709


I have seen the best performance (vs. capacity lost) when I OP my SSD's by 33%. At least 25% OP'ing is needed to see sustained performance (over time) increases if OP'ing at all.

See:
http://forum.notebookreview.com/thr...not-equal-op-space.759056/page-2#post-9743244


So, with your new SSD installed (and no other storage drive in the system) and your Windows Installer USB key used to install Windows 'clean' on your new SSD; OP the brand new SSD by seeing the actual MB available on your drive (yeah; this differs between drives) and multiplying it by 0.67 and create a new partition of that size (Windows will create another partition too, of course - let it). Go ahead and install Windows at this point and then install drivers as needed and do all necessary windows updates.

Install your programs and their updates too.

Now, install any additional drives you want. Format them (you backed them up first, right...).

Now, COPY your data to your freshly setup system.

Turn off System Restore.

Turn off the hibernation file.

Turn off the pagefile - reboot the system twice and verify that the above have taken effect and 'stuck'.

Do a mock run of your normal/heaviest workflow with a COPY of you data and see if you get any unexpected behavior from the O/S or your Programs. If your system doesn't hiccup with the pagefile off; leave it off.

Note that I would do these tests only after a clean install of Windows. As your system is right now; there is no point to see if any errors come up (you wouldn't really know the reason for them...).


With 33% OP'ing, free space of at least 150GB to 200GB (at least when you're doing your video editing sessions...) and a clean install of Windows with the correct drivers installed; it may very well feel like you have a new system in your hands.


Note too that the TB's written by themselves do not mean much. The type of writes that the drive sustained over it's lifecycle is important too. 22TB of random 4K writes is much more taxing on the nand than 22TB of sequential writes, for example.

With an indicated 67% life left; I would not be using it for my O/S + Program drive any more. Sure; smaller drives have been shown to 'handle' 500TB of writes or more; but those drives were not used as an O/S drive - nor where they tested for reliability either...

Say 'ty' to the use you got out of it but say goodbye asap...

Your data, workflow and system will thank you...

Continue using CCleaner... but do so after a reboot and after leaving the system idle for a few minutes...

And the error you got with IRST? I would put that down to the file corruption caused by your first drive dying on you...


Hope this helps.

Good luck.

 

Really...many many thanks for all your help!! to schdragga, namaiki and tilleroftheearth...you're the best dream for a person looking for help

So, let's go again by points:

- No schdragga, i've not disabled fast boot, but as far as I've read, it happens automatically when you disable the hibernation file as I did (using the command powercfg -h off)...is that right?

- The desktop icons is a weird thing...it's really random, and it happens when I move some icons together to the left bottom corner of the desktop (that is empty), and sometimes one random spot is not "filled" by the icon that i'm moving, but it displaces the others...as I said..weird (nothing is picked up if I select with the mouse as you said)
- The undeletable folder is also funny, I've just discovered that I CAN move it into another folder on the same drive C:, but also there I cannot delete it (it says that the element can't be found, that it's no longer on that path)
- The settings of both drives are default as in the post you linked.

- Dear tilleroftheearth, many thanks for your detailed step-by-step procedure to have my laptop truly healthy again I have understood everything, but I've some doubts:

My MSI GS60 has two M.2 slots and one 2,5" bay; and on the other hand i've a 2TB external drive for backups. Right now I've the Toshiba 128GB M.2 as C: ( SO and programs), and the Samsung 850 EVO 500GB M.2 as E: ( storage). The 2,5" bay is empty since the head crash of my old HDD. Because of my laptop model, replacing the M.2 is a hard work (for me), as I need to disamble almost everything, but if it's necessary I could do it again (as I did for installing the Samsung). What I would not like to do is to junk also the Samsung 850 EVO M.2, as it's just 4 months old, and it's working perfectly.

I can't afford right now one 1TB SSD, but I could go for another Samsung 850 EVO 500GB M.2 (could be another model) to replace the Toshiba and use it just for SO/programs, and leave the Samsung SSD M.2 for storage and my external 2TB drive for backups. I would have much more space in the new SSD that in the Toshiba, so I could OP it as you explained me .

I would prefer not to do some RAID 1 as I would loose to much storage.

Another similar option would be to buy a normal 2.5" SSD, but as I read 4 months ago, it's a little bit better to have them as M.2, is that right?

Update: It has happened again ...I was distracted working in "auto" mode, and I edited a picture that was in my lovely DESKTOP with Photoshop, and when I saved the changes it disappeared, like other random icons again (My PC, My Documents, Excell, Dropbox, etc.). I've not lost any other file, so don't worry, i'm not that stupid haha. So, we can deduct that somehow Photoshop is related with the problem (as I said, on the first time I maybe left it opened when I was cleaning temporal files with CCleaner...), and that CHKDSK has not solved completly the issue...

So, option 1 (reinstall Windows and clean start in the same Toshiba drive - and hoping that it was just a SO/software problem), or directly to option 2 (buy new M.2 SSD and clean reinstall of Windows and programs, and use second SSD for storage)? do you think that it's for sure a SSD problem? obviously the option 1 is easier/cheaper to do

Edit: option 3 would be to buy a cheaper 1TB HDD (WD Black?) as storage drive on the 2,5" bay, and use the Samsung 850 EVO M.2 for S/O and programs. What do you think?

Thank you very much again for your help!! I truly appreciate it!

 

I would not have an SSD and a HDD on a mobile platform if you can avoid it... The system is just slower like that to me (less 'snappy'. Not to mention no less durable than a purely mechanical drive based platform too.

I believe (from experience) that 2.5" SSD's are a better bet on mobile systems where cooling is limited vs. M.2 SSD's. The M.2 SSD can throttle itself and the rest of the system (CPU, GPU, etc.) in very short order. The high performance they're capable of translates into much more heat (and their form factor makes it harder to dissipate that heat outside the chassis...) than a physically larger 2.5" SSD. In the worst cases, the M.2 SSD can throttle it's speed to below HDD speeds... so no, they are not better than 2.5" drives, imo. At least not in a mobile chassis that doesn't have adequate cooling for the M.2 models.

Yeah; fast boot is disabled by disabling the hibernation file.

Photoshop is not the issue. Windows is corrupted via registry cleaning and a HDD failing with programs installed... Do a clean install and you should have no further issues like what you're describing.

If $$$ are very tight; you can continue to use the Toshiba 128GB SSD... but I would be saving up every penny to replace it with an MLC based model with 4x or 8x the capacity, asap.

I would still recommend to remove all drives except the one you're installing Windows to. After it is fully setup; add the other drive(s) and format them before first use.

You may want to use the EVO as the O/S and Program drive for now (and OP it as much as possible while leaving at least 100GB of free space on it too) - the Toshiba SSD can be used as additional storage (storage use is much less strenuous to SSD's than O/S usage) - but be sure you have multiple backups of all files stored on the entire notebook!

I'd like to repeat that this now seems like a Windows corruption issue; but I still wouldn't be trusting the Toshiba SSD with my stuff. Too many TB's written (user initiated and host initiated), too small... and a larger (MLC) SSD will have obviously better performance too.

Re-read what has been offered in previous posts; I don't think I can add too much more here.

Let us know how you make out too.

Thanks.

 

Hello again tilleroftheearth! Many thanks for your really kind help!

I've followed your nice advice, and have with me a new SSD 500GB 2,5" Samsung EVO 850 (yes, the same model, but not M.2 haha). As my laptop doesn't recognize PCI-e for M.2 SSD's, I thought that it was a better idea to get a 2,5" as you recommended me. The idea is to have the OS+programs in one of the Samsungs (OPing it as you told me), and having the files/storage on the other one.

I'm pretty busy right now because of a competition, so I would like to reinstall Windows + programs as soon as possible (because I don't want to loose any data), but I would like to avoid to disassemble aaaall my laptop in order to take out the "not reliable" M.2 Toshiba to save some time.

So just 2 final questions:

- Is there a way to install Windows from a USB-drive, in one of the Samsung SSD's without having to disconnect the others? all my data is already saved in an external drive, so I could format the Toshiba first and then install windows in one Samsung? will it work?
- Is it better to install the OS in the M.2 drive or in the normal 2,5" one? (same model)

Many thanks again!!

 

Great! After your competition, you'll be ready to get your system up to speed!

If you don't want to open up your computer (repeatedly), try the following:

• Physically install the new 2.5" SSD you just bought - but don't do anything with it in Windows.
• Make sure you have a backup of all your current/latest data before continuing.
• Boot from the Windows USB installer and select Advanced install options.
• Make a note of which drive (drive 0, 1, or 2) is the new SSD you installed. This is the one you'll want to install Windows to later...
• Now; for each existing drive; format each partition - and then remove that partition - do so until the whole capacity of the drive you're working on is 'unallocated'.
• When you have done so on each existing drive (remember; the new one doesn't need this done...) you should have a list of drives 0, 1 and 2 in the advanced installer screen and all of them will have no partitions on them at all.
• Hopefully; drive 0 (zero) will be the new 2.5" model. Select it and create a partition - it will tell you the number of MB's available.
  • Take that number and multiply it by 0.67 (if you want 33% OP as I recommend) and enter that number into the box.
  • Windows will warn that it may create additional partitions - let it.
  • After the new partitions are created, check to see that they are on the same DRIVE.
  • If they are; you're golden - install Windows, install the drivers, do all Win updates and install your programs (and their updates too).
  • Now, disable System Restore, Pagefile.sys and the hibernation file.
  • Run 'Automatic maintenance' a couple of times (the first time will take a longer time...), rebooting between runs.
  • Check to see that SR remains disabled.
  • Right Click on Computer and select Manage and Select Disk Management.
  • Create partitions on the remaining drives as required (I would still OP them... - you can always 'extend' the partition if you really, really, need the space).
  • Copy your data and...
• Enjoy!

If Windows creates a system partition on a drive other than the drive you're installing Windows to; I would not recommend to proceed with the install. You'll have to remove the drives physically to do it proper.

(Because if that drive is removed - Windows won't boot up).

I hope I have outlined the steps above clearly enough.

Good luck on your competition and also with your system too.

Take care.

 

You explained it perfectly!! many thanks again!!!

Just one question before doing it: what happens if the drive 0 is not the new one? can I change the order there? and what about installing the SO on the Samsung M.2? is there any advantage of cooling/performance for the 2,5"?

Many many thanks for all your patience and really kind help!

 

If drive 0 isn't the new one (the 2.5" EVO) but Windows Setup can create the hidden system partition and the C:\ on it; no problems. Only when Windows Setup can't create the hidden system partition on the same drive will you need to worry (actually; no worry; just remove all the other drives and start the install process again).

Huge advantage to the sustained performance of 2.5" SSD's vs. your SATAIII based M.2 drive when it comes to cooling/throttling issues. Assuming that both drives (both properly cooled) are equal in performance ( and they should be); the hotter drive will be worse in real world performance and also possibly throttling the rest of the components in your system too...

Remember that the C:\ has not only user initiated reads and writes; but also host initiated reads and writes - in addition to the GC and any other background tasks the SSD deems it needs to do to keep it's nand alive. When that same drive is used as a storage drive (only) - it is only user initiated reads and writes it needs to account for - and those will be far fewer than what the host (Win10 in this case) needs to do with the drive. This will keep it much cooler and less of a heat source to the rest of the platform.

Hope this was clear?

 

Hi dear tilleroftheearth!

Many thanks for the explanation! it was helpful! I installed Windows in my new 2,5" EVO without any problems, and I checked the temperatures and it's indeed some degrees cooler as the M.2, so perfect! I updated Windows, installed all the programs I needed (Autocad, Adobe Suite, Office, Dropbox, etc) + Nvidia driver + MSI drivers from msi.com + Bitdefender Free + Malwarebytes Premium

But it was just until yesterday, when suddenly I had some blue screens with the error "critical process died". I look into the events viewer, and discovered that the driver of my USB-WLAN TP-LINK tl-wn722n (based on atheros), was failing. After it I read that it's a common problem, as Windows 10 is not fully supported by that TP-LINK....but I didn't understood it completly, as i've used it for 2 years and W10 without problems...

But anyhow, after desinstalling it and not using anymore, the blue screen appeared 3-4 times more. And I found more "errors" and "warnings" in the events viewer, like:

Error
The application-specific permission setting does not grant the Local Activation permission for the COM server application with CLSID
{D63B10C5-BB46-4990-A94F-E40B9D520160}
And APPID
{9CA88EE3-ACB7-47C8-AFC4-AB702511C276}
To the NT AUTHORITY \ SYSTEM user with SID (S-1-5-18) in the LocalHost address (with LRPC) running in the application container with SID Not available (Not available). This security permission can be modified by using the Component Services administrative tool.
Supposedly solved


Warning
The speed of the 1-8 processor in group 0 is limited by the system firmware. The processor has shown this reduced performance status for 25 seconds since the last report.
Still happening

Error
The DbxSvc service could not start because of the following error:
The system can not find the file specified.
Still happening

Error
0x800700B7 in the AppContainer profile because it could not register the AppContainer SID.
Still happening


As I wasn't sure about what had corrupted my computer (I think that this time the SSD's are not the problem and they're working well), I decided to format and clean reinstall Windows again, and go slower while installing programs/drivers. Right now, after 5hours of using it, just the errors/warnings that I wrote that are "still happening" are still there, but no blue screen for the moment...

Aaaah I hope that my computer let me to use it and work with it without any other problem! Would you recommend me something? Should I try to fix those errors/warning? what do you think about using both Bitdefender Free + Malwarebytes Premium? (they are supposedly a good mix) should I be careful while installing some software/driver?

Many thanks again! I hope that I can leave you in peace soon

 

victorgm, sorry to hear about your continuing problems.

Could you link the notebook you are using and any updates you've done (like RAM, etc.) to it? What CPU does it have? What is the RAM capacity?

If you can do a clean install and just use the drivers Win10 offers; that is what I would test next.

Myself: I don't use any additional A/V software other than what Win10 comes with. I've never (ever) had luck with third party software to protect/babysit what I'm doing with my system(s).

Have you checked the memory of the system for errors? It may be a bad stick of RAM (or both...) that is leading to this end result?

If there is any issue on a platform that isn't fixable; I would not continue using it.

Could the M/B be going bad on your system - this will also give corruption issues - can you remove any hardware that the drivers are failing on?

Also; did you leave the old 128GB SSD 'unallocated'? This may also be a clue to fully remove it from the system.

Lots of things to test and check; but it will be worth it to get a stable and dependable system again.

Hope some of this helps.

Take care.
