    The thing is I have no idea where to update LhdX64.sys becuse I downloaded recent version of Energy Managment from Lenovo support site using this URL http://download.lenovo.com/consumer/.../em8180214.exe

    I've uninstalled DaemonTools and I' ve used SPTD, I checked registry and the value data of Start was 4 as in manual guide so should I remove it as in guide or leave it like that?

    For what it's worth, the driver Lhdx64.sys has stood out to me on numerous machines as being the last possible software culprit possible. I'm not so sure that it is part of Energy Management download, but if you know something about it more than I, then more power to ya.

    I've been suggesting that people contact Lenovo support to get it updated, and I have yet to hear back from a single one that needed more help.

    Perhaps Usasma and I are onto something with that driver. In any case, he has done extremely well for you in this thread already.

    If you are of a mind to perform an experiment, we can try removing the driver to see if that helps.
    Please be advised that doing so could render your system unbootable.
    We'll take appropriate precautions to ensure you can recover from this - but be sure to back up your system before trying it.

    Here's how:
    1) Create a Restore Point using System Restore
    2) Create a Repair disc (Recovery Drive in Win8.1):
    Win 7 - Go to Start...All Programs...Maintenance...Create a System Repair Disc
    Win 8 - Press "WIN" and "R" to open the Run dialog...type "RECDISC" (without the quotes) and press ENTER
    Win 8.1 - Go to the Start Screen and type in "recoverydrive" (one word, without the quotes). That will start the recovery drive process. You will need a USB drive of at least 512 mB - and all data will be erased off of it.
    3) Test the System Repair disc/Recovery Drive to make sure that you can get to the System Restore entry when you boot from the disk/drive (you may also want to try actually using System Restore to make sure that it works)
    4) Download this free program (Autoruns for Windows) and use it to disable any instances of Lhdx64.sys that are starting (or any other Lenovo HD Disk Driver entries) (DO NOT DELETE - only disable by removing the checkmark in the left hand column)
    5) Check in Device Manager (to include showing hidden devices from the View menu item) and ensure that any instances of Lhdx64.sys (or any other Lenovo HD Disk Driver entries) are "Uninstalled" (DO NOT DISABLE THESE).
    6) Check in the Services applet (services.msc) to be sure any instances of Lhdx64.sys or any other Lenovo HD Disk Driver entries are disabled.
    7) Go to C:\Windows\System32\drivers and rename the Lhdx64.sys driver to Lhdx64.BAD (search the hard drive for it if it's not in C:\Windows\System32\drivers).


    In the event that the system doesn't boot:

    1) Boot from the System Repair disc/Recovery Drive and use the Command Prompt option to rename Lhdx64.BAD to Lhdx64.sys
    Code:
    ren C:\Windows\System32\drivers\Lhdx64.BAD C:\Windows\System32\drivers\Lhdx64.sys
    2) Boot from the System Repair disc/Recovery Drive and use the System Restore option to restore the system to a point before the changes were made.

    Good luck!
    Should the system boot successfully without the driver, run it for a while (several weeks) to see if the BSOD returns.
    If it doesn't boot successfully, then you'll have to use the recovery procedure in the above instructions.

    I'm working now without any bsod so probably all your advices help me, I'm realy grateful for your interest and help. Probably in a few weeks will be clear if there is any extra problem, so the thread has been exhausted. Again thank you very much.

    Did you remove the Lhdx64.sys driver as I suggested above?
    Do you think that it was the source of your problem?
    I'm happy that you are no longer having problems!

    Well I was trying to get any information from Lenovo Support about this driver, unfortunalty I got only 1 link from some Comunity Moderator Malware scan of lhdx64.sys (Disk Driver) ab35ce3335ba8bc7b49fc9c81b1e6a852fe853b0 - herdProtect
    I didnt get any information how to update it or remove or with what application it is installing. I was thinking about uninstalling all drivers and check if this one is still the part of a system, anyway I had 1 more bsod a few days ago so maybe good thing is to do some experiment uninstall all, then install 1 by 1 (maybe I'll be able to discover what is installing this one driver) and after this just format c:
