    BSOD Can't boot to safe mode or desktop


    Hi all,

    I put my PC into sleep mode before heading out last night and upon my return I was presented with a BSOD. So I'm not actually sure if it went into sleep mode.

    I'm kinda at a loss as in to what is causing my bsod. It happens after the Windows logo, but doesn't return any errors messages besides "SYSTEM THREAD EXCEPTION NOT HANDLED". Then it reboots.

    Upon reboot I can access the Troubleshoot section and go into the advanced options. I've tried:

    - Start-up repair: This shows "Attempting repairs" and then says "couldn't repair your PC". Log file I:\WINDOWS\System32\Logfiles\Srt\SrtTrail.txt. I've accessed this txt file via cmd and the only thing I can see in here is:

    "Repair action: System files integrity check and repair
    Result: Failed. Error code = 0x490"

    - System Restore: This also fails with "System restore failed while restoring the directory from the restore point. (0x80070091) %ProgramFiles%\WindowsApps.

    - Safe mode: BSOD "SYSTEM THREAD EXCEPTION NOT HANDLED". Then it reboots.

    - Command Prompt: sfc /scannow returns "Windows Resource Protection could not perform the requested operation". chkdsk /f returns "Windows cannot run disk checking on this volume because it is write protected"

    Any assistance will be greatly appreciated.

    Hi, I'll just throw in a couple of comments and leave the BSOD to the experts:

    1. chkdsk on your system disk:
    From an admin command prompt
    [Windows key + X, click command prompt (admin)]
    chkdsk C: /F
    Your PC will need to restart.
    Post back the result, which you can get after a restart as follows:
    How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

    2. System Restore error 80070091: there is a very long thread on this (I happened to start it) with a solution in the first couple of pages. I understand that is one MS is working on.

    I would recommend you check your disk using Crystal Diskinfo (free, easy to find, also portable)

    Hi Dalchina

    Thanks for your response.

    So I managed to fix it by system restore. However, to fix my system restore, I had to rename the "WindowsApps" folder via Command Prompt in the Advanced options to "WindowsAppsOld".

    Steps
    1) Troubleshoot/Advanced options/Command Prompt
    2) Type the following: attrib "c:\program files\windowsapps" -h and hit enter.
    3) Then type the following:
    rename "C:\Program Files\WindowsApps" WindowsAppsold and hit enter.
    4) Reboot and try system restore again.


    Thanks

    Great- I'd still advise you to do the disk checks as a matter of course, as you may have no idea at present as to the integrity of your disk of file system (two different but somewhat related things) or the underlying cause of what happened.

    You could also check your event log at that time, or perhaps easier, your reliability history (type 'reli' into Cortana's search bar).
