Windows freezes at Logo screen, blue screens and restarts, nothing works. RRS feed

  • Question

  • Well, the problem began when the Disk Defragmenter wouldn't work because the Task Scheduler wasn't working. I followed a video tutorial where I went into the registry and I believe I only changed the registry for the event log to automatic from disabled. Afterwards, the Disk Defragger started to work and I let it run overnight.

    The next day after work I noticed the computer was on a black 'Windows Error Recovery' screen and when I attempted to run the startup repair it flashed a BSOD and restarted itself. The BSOD, it turns out, read:

    "A problem has been detected and windows has been shut down to prevent damage to your computer.

    If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

    Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

    Technical information:

    *** STOP: 0x0000007B (0xFFFFF880009A97E8, 0xFFFFFFFFC0000034, 0x0000000000000000, 0X0000000000000000)"

    I attempted to restart the computer into Safe Mode and the computer froze on ClassPNP.sys and crashed.

    The Startup Repair eventually succeeded to run and came up with a message saying:

    "Startup Repair cannot repair this computer automatically...

    Problem Signature:

    Problem Event Name: StartupRepairOffline
    Problem Signature 01: 6.1.7600.16385
    Problem Signature 02: 6.1.7600.16385
    Problem Signature 03: unknown
    Problem Signature 04: 577
    Problem Signature 05: AutoFailover
    Problem Signature 06: 1
    Problem Signature 07: BadDriver"

    The Recovery disk I got with the computer is for Windows 10 when I had Windows 7 pre-installed on it. I reached out to the computer's manufacturers asking for a Windows 7 specific recovery disk and they gave me a link to the Windows recovery page and when I input my product key it gave me an error message saying that since it's a pre-installed product that I need to go to the manufacturer.

    So.

    I have come to you for advice. Please Help.

  • Regedit editing...Bad Idea...If possible,reset the registry to its default setting(s)..Also,to run defrag,open cmd,type: Defrag C:  always run thru cmd,& before defrag in cmd,type: CLEANMGR 

    From this point,start pc in safe-mode with cmd (F8) key,type:  Sfc /Scannow  if it runs,or after,type:  CHKDSK C: /F   agree to restart,type: EXIT  restart pc

    Also,for driver verification,in run or cmd type:  SigVerif

  • The reported bugcheck 7B was inaccessible boot device.

    1) What are the status of the files on the computer?

    a) backup image?

    b) backed up files to another drive or to the cloud?

    c) no files backed up

    d) files are unimportant so a reset remove files or clean install could be performed?

    2) Find two flash drives that you can format (> or = 8 GB).

    3) On a working computer create a bootable windows 7, 8, or 10 iso:  (a windows 7 iso is preferred unless you are considering upgrading to windows 10)

  • Hi,

    Please try Last known Good in advanced options.

    If the issue still appear after LKG, boot into WinRE, try the following commands: 

    1. Run chkdsk to check disk

    2. run the following to fix mbr, bcd

    bootrec.exe /fixmbr

        bootrec.exe /fixboot

        bootrec.exe /scanos

        bootrec.exe /rebuildbcd

    3. Run startrep.exe / sfc.exe in WinRE to scan the integrity of operating system files.

    Best regards,

    Yilia

  • Hah, no kidding!

    Unfortunately, when I try to open in Safe Mode with Command it stops at ClassPNP.sys and crashes out.

    Thanks for the reply though!

  • Hi,

    Use Windows installation media to boot into WinPE and run the command above.

    After insert the media, click repair my computer and choose command prompt.
