  1. win 10 BSOD ....21a


    I was running a simple install of some wd my space software and it seemed to be taking a long time to install. At the end of the install it said I needed to reboot the system. When I rebooted, I was presented with a blue screen of death with …21a error.

    I have tried several things to repair the problem, nothing worked. Finally created a usb disk with a iso image of win 10. Is there so way to restore/fix win 10 without affecting my photos and music files? it isn't clear from the instructions. I ran the iso restore win option but it didn't work.

    I just ran the win shell and it seems that all the files are on the d: drive, could it be that the c: drive was changed to d:?

    Please advise, Charlie

    :)

    Win 10 BSOD while using

    Did upgrade to Win 10 over a month ago. This morning my Lenovo T410 laptop had the BSOD with Error=0xc000000f on it (it does backups overnight). I've run diags on the hardware (mem, motherboard bus, PCI bus and HDD) all PASS. Tried using my repair disk
    (built in Jan with Win7) and was unable to recover. I checked for bad sectors and found none. From CMD prompt I did DISKPART and LIST VOLUME and all volumes say HEALTHY but I see that my C: drive (primary partition) says it is RAW (instead of NTFS). My backup
    media is a network attached (NAS) disk and I used Cobian 11 Backup. Not sure what my next step would be. Looking for suggestions before I have to restore to Win7 and re-upgrade, etc.

    Random BSOD while browsing internet


    BitDefender is nothing special. mwac.sys causes BSODs anywhere.
    A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
    In that very thread, the suggested action apparently worked.

    The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
    As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
    That is why I posted that my suggestion may work, or may not. Let us see where it goes.
