Yes, finally fixed the SSD freezing my computer!

TL;DR If your computer is freezing after installing an SSD change from AHCI to IDE mode in the BIOS.

Argh! This has been driving me slightly mad for a while. I bought a Samsung 840 SSD a few weeks ago to make things a bit faster. It does too, mostly to the boot up (which I rarely do, this machine is on 24×7) but it feels smoother in day to day tasks too.


I keep the Lightroom catalogue on the SSD, Windows 7 is on there too but most apps, all games and all photos are on other drives.

It worked fine for a while but then it started freezing and stuttering without warning. It was usually when I had a few dozen Chrome tabs open, Firefox running, Skype, xchat, and various services going. The mouse cursor would disappear and the keyboard would stop working for about 5 seconds. Then the problem would go away for a while.

It came back this morning with a vengeance. If I reloaded a browser tab I was guaranteed to freeze my PC.

I had gone searching for solutions before. I’m not the only one with this problem but forum threads were usually:

  • Filled up with replies from people saying, “me too”.
  • A few brave souls asking for log files
  • Suggestions to update firmware and BIOS
  • Solitary pleas for help.

I made sure my SSD firmware was updated (it was) and updated the BIOS of my ASUS P8Z77-M motherboard for the first time to no avail. No change. I was getting ready to put Windows back on the original disk.

Finally, one last desperate search later, I came across this thread and in the same search this page suggesting two methods I hadn’t tried. I did not try disabling LPM (some sort of power saving mod) but I did change the SATA mode from AHCI to IDE. Supposedly the SSD won’t work as well, but it fixed the stuttering and freezes, probably because it apparently disables power saving mode too, or so I’ve read.

Phew. No more stutters! If I hit any performance problems I’ll try the LPM trick with the registry.

  1. My PC started freezing again this morning, so I checked the event viewer and found this error I had noticed before but discounted:

    The description for Event ID 14 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

    If the event originated on another computer, the display information had to be saved with the event.

    The following information was included with the event:


    I’m not the only one with this error and the solution seems to be to downgrade my Nvidia driver to 314.22.

    Hopefully this will fix the freezes. If it does I’ll enable AHCI again.

    1. Just letting you know that you saved my computer with this single comment : I had exactly the same issue, and reverting to 314.22 fixed it. Thankyou so much!

      1. Glad I could help Melibellule! I’m not upgrading my Nvidia drivers unless I need to, and since I have no interest in play Battlefield 4 that won’t be any time soon!

    2. For me this didn’t fix it, but rather disabled my pc from even booting 😀 My solution was to apply the setting “never put hdd to sleep” in the control panel. If you look SSD, never allow disk to sleep on the web, you’ll find a lot of threads where ppl had they’re pc freezing up.

      1. you can’t do this type of change (AHCI to IDE) after you installed your OS,of course it won’t start properly then. You must do it BEFORE you install your OS. However, I have read somewhere that there IS a workaround so that you can keep the old OS, something with a registry and drivers, not sure – google it and you’ll find it quickly.

        1. it can dude. you will found the way to change it even after you installed your OS but as much as i know (and already did) it only work on win7/8/8.1. you can found it so easy on google.

          in win7 you can change to ahci right away because it locked in regedit so just unlocked it there will let you change to ahci with out blue screen after boot. when in win8/8.1 it not really locked, it just need you to boot on safe mode after change to ahci in bios that all you need to do.

          and finally you can switch back and forth your sata mode without to reinstall os. just study more on google, people do this for years.

        2. You’received wrong, it’seems risky, but it’seems possible. I’d did that a lot with hp laptops and desktops at my previous job. You need to have the proper drivers and select the right chipset, change the mode in the bios, then reboot and if everything was correctly configures, it will work.

        3. nono, I wanted to let you know that you helped alot of people out there with this problem!
          most people didn’t even know this..
          i contacted nvidea and they are now aware that this might be the problem they will help out others with this information, most people blamed nvidea and windows software for this problem with out knowing what it really is that caused this to freeze up, even I tried really everything!!! I just can’t beleave this problem was so easily solved!! thanks again!

      2. thanks I’m gonna try this out aswel i just changed it from 20 minutes to 0 see if it works 🙂
        i don’t have the same issue as you guys but my computer freezes up when i play a game on my hdd my ssd is fine but for some reason it can not communicate with the other drive i think its because of this, i didn’t even know this was a option so thank you 🙂

      3. Trying this solution now!! The settings for HDD on battery and on power were both set to 20 min which is about the amount of time it took for my laptop to freeze all I/O after use. I’m really hoping this fixes my issue. Thank you for the comment. If not I will move on to the next suggestion. I installed a Samsung 860EVO PRO about a year ago and the I/O freezing issues started happening soon after.

  2. I had a huge problem with NVIDIA driver. My computer would crash, stutters and freeze for no reason. I ran multiple tests everything came out with no errors. I got 840 SSD thinking I have an HDD issue, no way the same problem kept happening all over again. As soon I rolled back NVIDIA driver to 314.22 since no issue what so ever.

    1. I tried the Nvidia driver rollback did not help. I also tried tried the regular edit for that data port Andes that did not help either. Finally I installed the Intel rapid device driver which upgraded the sata hdd drivers and that worked. But I had to re clone my original drive.

  3. Same problem, but I can’t revert to anything older since installing GTX 750 Ti which requires the newest drivers. Does anyone have any other solutions aside from removing the video card or SSD?

    1. I had to upgrade to the latest Nvidia drivers (mining Dogecoins) and my SSD problems haven’t come back. Maybe go back as far as you can and then forwards again?

  4. It turns out that the newly released video card was causing the instability. Apparently it can’t be installed prior to windows updates, or any updates really. I had to re-install windows without the card installed then grab windows update, then do a clean uninstall of the ATI drivers from the update. After that I installed the card and updated the Nvidia drivers. Everything works great now.

    I suppose this wasn’t a related issue, but we did have very similar symptoms. I’m just glad the SSD isn’t bad. =D

  5. I had a similar problem. Installed an SSD (Samsung 840EVO mSATA) in my 4-years old Windows 7 pc (still SATA II), and whenever I wanted to copy data to it, it froze completely. I tried your suggestion of switching off the AHCI in the BIOS, but for some reason the pc refused to boot after that. So I had no alternative but to keep AHCI selected.

    Then I phoned Samsung and they managed to solve the problem. Apparently there are problems with nVidia’s SATA drivers. Samsung suggested I uninstall the current driver (control panel, device manager, SATA drivers) and reboot the computer. This would allow windows to install a driver by its own (no idea which version though).

    Much to my surprise this solved the entire issue!

    1. This actually worked for me. The issue that I was having was that it was a new install. So I did some troubleshooting and performed some things:

      1. Disabled Aggressive Link Power Management

      2. Performed the step above that you mentioned (except this is an asus motherboard, and it had somehow installed Intel SATA drivers. Now it has Standard AHCI 1.0 Serial ATA Controller installed, which I find is much more stable)

      3. I downloaded Samsung magician to make sure that the firmware was up to date, which it was.

      1. Thank you so much for suggesting Samsung magician. It turned out that my firmware needed to be updated. My computer kept freezing after 10 minutes. After updating the firmware it is running just fine. I thought I was going to have to reinstall Windows. Thank you so much.

  6. I’m having problems with my computer too in Windows 7. I am running windows directly off of an SSD (240GB’s), and it was already in IDE mode and I just turned on S.M.A.R.T. with the same problems still occuring. I’m considering moving to Linux because of this, it’s fucking annoying as hell. Or maybe ill just run Windows off the slowest HDD I can find on the market. Damnit. Thanks for the post, at least theres hope.

  7. I just put a new PC together and installed Win 7 on an SSD. While I’m downloading and installing various drivers, Win 7 will randomly freeze and I have to hit the power button for a hard reset. I didn’t update Win 7 before installing the graphics drivers. I wonder if this is what’s causing the problem. Will give it a go tonight.

  8. I owned a Kingston V300, and had the same problem with freezing which mainly occurs while streaming youtube videos.

    I solved the issue and I think 1 year later the problem came back again, now I not only have problem streaming youtube videos but also using the computer

    When i stream videos, it hangs, the sound becomes blurry and a buzzing sound can be heard it is super loud.

    Other then using youtube, my PC has the occasional hang for 20-30s, which is kind of annoying, hoping after reading this i will solve this issue.

    i suspect its the Nividia drivers and will consider rolling back the drivers since i nva had this problem for a year and it must have gotten to do with the updates….

    1. I have the same problem like you, and i tried evrething and still the same problem, but the evan bigger problem now is that i removed the SSD and my hard drive acts the same, freezes like hell, and i tried to reset bios by default and clean installs of win 7 and 8.1 same thing

  9. For those of you who could not fix the problem, it seemed to be Intel AMT in my case (Lenovo T410s). Try to disable it in BIOS. AMT probably was probably not compatible with my SSD.

  10. I also have a Samsung 840. I also have a PC that freezes (once every day or two it locks up and I have to reboot it). When the computer is frozen, it is in a strange state. It’s not a full hard lock. It still responds to pings on the network. I can move the mouse around (if the screen was on when it messed up). *Sometimes* I can press the power button and it will go to sleep mode, and then wake up and be fine. But mostly it’s just generally broke and I have to reboot it.

    I’ve spent a couple of months swapping out pieces trying to find the problem. Currently investigating the SSD.

    I was sure it was the graphics card for a while because of other things. I have an NVIDIA graphics card like many people in these comments. However, after switching on Optimus (using the built-in Intel GPU to drive the display) and disabling the NVIDIA card, the problem still occurs, so I’m pretty sure it’s not that.

    I followed your advise switched to IDE instead of AHCI in the BIOS and it’s good so far. I need to wait a couple of weeks before I’ll really trust it. You just might have saved me a lot of trouble here.

  11. Hello Guys; I also experienced the same problem when I replaced my old hard drive with ssd samsung 840 evo, my laptop keeps crashing sometimes especially when I open alot of browsers and installing a software altogether. I also experience freezing when I play an HD video with a size of 13 Gig. I experienced it for almost a month now untill I found this forum and yet there is no concrete solution to the problem yet. Others say that they changed the sata mode from AHCI to IDE which is wrong because SSD will only work on its best performance in AHCI mode. Others also say to downgrade the Video card driver. You know guys I recently checked the samsung Magician software and I found the problem at the System management particularly the OS optimization I set it before at Maximum performance and since hibernation mode is activated in this kind of optimization it causes the problem because it consumes 75% of the ram memory therefore it causes the system to crash when I opened so many browsers and freezes my video when I played it. I changed it to advanced and disabled the hibernation mode and configured the virtual memory to 4.5 gig I hope this will solve our problem

  12. Update from my previous post. With IDE mode enabled, my machine lasted for 9 days before crashing again. I was so hopeful that it was fixed, but in the end, this was not the solution.

    Turned out I had one (or more) bad RAM modules. MemTest86 confirmed this. I replaced them all and the problem seems to be resolved.

  13. The thing that fixed it for me was one of the following.
    1. I uninstalled everything Nvidia.
    2. Reset the bios (turn off ur pc, remove the battery, wait a minute then plug it back in)
    3. Unplugged every hardware i could and plugged it back in (graphics card, memory, SSDs/HDDs etc.)

    when i booted my system back up, it started a disk check. When it finished, pc restarted and everything worked fine.
    One thing i noticed is that google chrome was warning me of some suspicious activity and couldn’t open any websites, and it seems some stuff got reset in chrome (my download location, the “allow fullscreen” for video streaming) but i’m guessing that cuz of the disk check, plus my skype was “corrupted” and couldn’t connect. After a new restart everything worked fine. Then i installed the nvidia stuff again.

    Hope this helps.

  14. The solution here is NOT the right one, it works by side effect. I found out that with some motherboards, “RAPID” technologies (Intel or Samsung) were causing freezes.
    * Samsung : in Samsung Magician, disable RAPID option
    * Intel : Uninstall Intel RAPID software

    Disabling AHCI indeed disables the RAPID option on Samsung Magician, but this is a bad solution because you loose many of the benefits of the SSD wihtout AHCI.

    Hope it helped.

  15. @ Ninj, I had RAPID disabled in Samsung Magician – freezes occurred less for a time, but after they again started to appear more often. For sure disabling RAPID was not the solution for me

  16. From Spain, with a Kingston v300, same problem…not sure if Nvidia Driver or anything else. It was working fine after some issues but I plugged ssd and hdd in SATA 3 and it was working propperly. But freezing started again…I will downgrade Nvidia driver, turn off AHCI and check. I will post results…hope we can find the solutions cause I cannot play HOTs withoit freezing.

  17. I’m leaving this reply in case it might help someone else. I have a decade-old DELL Inspiron 6400 (1505) laptop that I decided to put some juice into now that SSDs are dirtcheap. So I bought a 120 GB Kingston v300 SDD and a cheap Shenzen caddy from eBay.

    The laptop uses a slim ATAPI port for the optical bay and does not suporte AHCI mode. So what I have available are IDE/PATA speeds, I get about ~60 MB/sec writes with the SSD mounted in the caddy. I opted not to migrate the OS to the SDD and to use SDD as primary because then I wouldn’t be able to use hibernation without severely wearing down the SSD as hiberfil.sys can only be written to the Windows drive.

    Problem is, I would get freezes and stutterings several times / minute whenever the drive was accessed (and sometimes even when it was not), making the entire system unusable. I watched the task manager, the CPU load would be 0 while the freeze lasted — basically there was nothing to do because something was hanging the process. I upgraded the SDD firmware, tried installing Intel Rapid Storage Technology (RST) drivers (that turned out no to work on my system), disabled LPM from the advanced power settings menu and via the registry method, nothing worked.

    What fixed it was disabling TRIM. Turns out, in my system TRIM did not play well with the old, existing hardware. So that’s that.

    To turn TRIM off:
    fsutil behavior set disabledeletenotify 1

    To turn TRIM on:
    fsutil behavior set disabledeletenotify 0

    To check TRIM status:
    fsutil behavior query DisableDeleteNotify

    (Might seem counterintuitive, but 1 = TRIM OFF, 0 = TRIM ON).

  18. I realise this is an old article, but its the first that shows on Google, any way, I had this problem of constant freezing and lock ups, I reformatted my ssd 3 times and still had no luck, installed in ahci and ide with no luck on either. I uninstalled and reinstalled my nvidia drivers as my computer would say the nvidia drivers had crashed and been recovered, and then took my graphics card out to use on board graphics, but the Intel drivers kept crashing too, until finally, I realised that it was my creative e-mu 404 audio desk crashing my PC, if I had it unplugged, my PC would run fine, if I plugged it in, it would crash. Turns out my USB port wasn’t liking the fact the e-mu is powered externally, I’ve run it through a USB hub now and it all works absolutely fine.

    Check your USB peripherals people!

  19. I’m in installing a Samsung 850 Evo 500gig on an Asus z77 Windows 7. It freezes a few seconds into loading Windows. Help.

  20. I have freezing problem too with my old laptop when I bought Silicon Power SSD (I was using HDD before, it was slow but stable). I contacted the Silicon Power support and they told me that when u are using SSD, it is recommended that you set up AHCI mode in BIOS. Also they told me that if I bought new Silicon Power SSD, there is no need to upgrade the firmware. But the problem ocurs in AHCI and in IDE mode.

  21. I also searched high and low for a solution and was directed to change AHCI to IDE in the BIOS. unfortunately where I had a BSOD I now have a gently whirring fan and an unresponsive black screen. I’m unable to summon my BIOS to reverse my changes and fear my data is lost for good. (I have so much crossover on various clouds I’m not sure what’s backed up anymore, but I know it isn’t everything).

    How can I fix this blasted laptop? All I wanted to do was rollback to 7 from 10 because Kaspersky won’t guarantee my safety on 10. Guess it doesn’t really matter now, does it?

  22. Thank you very much to all.
    Finally i manage to save my PC Changing BIOS mode from IDE to AHCI and reinstalling operating system.

    Reading this post just save my PC. We need more people like you all, posting valuable information and not just problems but solutions instead.

    Thanks Again!

  23. To fix and keep your SSD as an SSD instead of switching to HDD or disabling RapidMode is as soon as your PC boots you have enough time to open TASK SCHEDULER and quickly navigating to the SAMSUNG task and deleting it.

    Works every time.

    You can still use Magician if you open it manually.

  24. Thx !
    I have a Lenovo Z500 and I put a SSD Crucial MX200 and I encountered the same problem.
    I changed in the BISO AHCI option to “compatible” and disabled LPM (register) and it works wonderfully.

  25. We must let the BIOS to AHCI active option.
    For the Lenovo Z500 I have this version:
    Intel (R) 7 Series Chipset Family SATA AHCI Controller

    I replace “iastor” with “iaStorA”

    [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ iaStorA \ Parameters \ Port0]
    “LPM” = dword: 00000000
    “LPMDSTATE” = dword: 00000000
    “DIPM” = dword: 00000000

    [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ iaStorA \ Parameters \ Port5]
    “LPM” = dword: 00000000
    “LPMDSTATE” = dword: 00000000
    “DIPM” = dword: 00000000

    See :

    To return to AHCI if you have a problem:

    Start Regedit and look for this line:

    HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ storahci \ StartOverride

    0 Change the DWORD value from 3 to 0.


  26. I changed from AHCI to IDE in the BIOS as per this post because of the SSD hanging issue. PC rebooted and said it couldn’t find the operating system and was going to restart. PC powered off and I haven’t been able to get it back up. All that happens when I press the power button is the HDD lamp stutters (3 flashes repeating). I’ve reset the BIOS but still nothing happens. I’ve put a different IDE HDD in without any luck. PC completely dead except for the flashing HDD lamp. Anybody got any clues to how I can get the BIOS back up??

  27. This may or may not help people but I’ll leave through trial and error what worked for me in the hope it might help someone else.

    I have a dual boot PC with Windows 7 and Windows 10 installed on a Crucial M550 SSD and an Asus P6X58D-E motherboard (I also have other non SSD hard-drives in my system). Both OS worked without issue in IDE mode but I enabled AHCI through the BIOS to speed up the drive. Windows 7 was fine but for Windows 10 it introduces a major issue that froze the PC when it was idle for a few minutes. The mouse would move but it wouldn’t respond and had to be rebooted. No change of LPM or HIPM/DIPM settings would fix it and I also have the latest BIOS and SSD firmware as of Nov 2016.

    As suggested above, I was able to switch between IDE and AHCI via a first boot in to safe mode to load the correct drivers each time and then a further reboot.

    However, in the Asus BIOS for the P6X58D-E there are TWO settings for AHCI and as soon as I used a combination of IDE and AHCI rather than just AHCI, the freezes stopped happening:-

    Storage Configuration -> SATA Configuration [Enhanced] -> Configure SATA as [IDE]
    Advanced -> Onboard Devices Configuration -> Marvell 9128 Controller [AHCI Mode]

    The combination above loads a combination of ATA Channel, Intel(R) ICH10 Family Serial ATA Storage Controllers and Standard SATA AHCI Controller for my hard-drives under IDE ATA/ATAPI controllers. The AHCI configuration that was freezing just loaded two Standard SATA AHCI Controllers.

    I bench marked the SSD in this configuration and it is running at super fast speeds of AHCI (400Mb/s) but with the same stability I had in IDE mode.

    Good luck – I was scratching my head for this for hours!

  28. Had major freezing issues. Mouse would lock up and even scroll/num lock wouldn’t toggle. If audio was playing, it would continue the last played sound during the freeze.
    My freezing happened after an update (either AMD drivers or Windows 10 update. can’t remember).
    AMD FX-3850
    32 Gigs of Ram
    Samsung SSD EVO 850
    SanDisk SSD
    Toshiba HDD
    Windows 10 Pro
    The only solution to remove the Toshiba HDD. I guess mixing SSD and regular HD causes problems on Windows 10.

  29. I have read all the diverse experiences in this thread to date. I am having many and different issues ( one time I almost reached the point of authenticating my windows 16 digit product key ) trying to fresh install win 7 pro to a Samsung Evo SSD in an Acer Ferrari One 200. Because of the variety of issues / different points I am locked up or frozen out … I get I have given up with the SSD for the time being ( If I achieve success with an IDE drive I will try and clone that to the SSD) Meanwhile I think this is just Samsung building products for Windows and Intel but AMD ( The processor in the Ferrari) being left out of the loop. In other words its politics !!!!

  30. Hi, I have an Asus Z87-DELUXE motherboard with item and ASMedia SATA controllers. Unplugging all devices from the latter resolved many issues I’d been having with Windows and various devices, including GPU driver installation
