    BSOD - DVBT USB Tuner


    Hi All

    I am not 100% sure it is the USB Tuner, but this is what it is looking like to me, so hope someone can look at these logs and confirm

    I have been having the BSOD every day for the last 4 days now and that is the only thing I can see that changes
    The tuner is working fine until I get the BSOD

    Tuner is recognised in device manager under a sound and vision device
    No problems reported with it
    I get a BSOD (just seems at random times, not when I am using the device)
    When it restarts, the Tuner has had a driver change and moved into the USB category with a warning saying device failed to start
    Change driver back and all works fine until I get a BSOD again, then repeat

    Hope someone can have a look or give me some pointers on what it could be

    EDIT:Not sure how the logs work, but last crash was approx 9:15am today

    Thanks

    Hi paulsalter,

    The crashes are caused by a driver called cydtv.sys which seems to be a USB driver from Tuner.
    Please update the drivers of this USB.
    Code:
    *** WARNING: Unable to verify timestamp for cydtv.sys
    *** ERROR: Module load completed but symbols could not be loaded for cydtv.sys
    
    
    0: kd> lmvm cydtv
    start             end                 module name
    fffff801`70ab0000 fffff801`70b69d00   cydtv    T (no symbols)           
        Loaded symbol image file: cydtv.sys
        Image path: \SystemRoot\system32\drivers\cydtv.sys
        Image name: cydtv.sys

    Many thanks for the quick reply

    I did a check for drivers for the device and they have a win 10 compatible one
    This has now been installed and all seems to be functioning fine

    however the cydtv.sys file is the same version as before

    I will monitor it for a few days, could have been corruption that reinstalling has fixed?

    More likely is the date the problem.

    Is this something that can be fixed?, or do you just mean its too old

    Prior to last Thursday I have had no problems with it, no crashes in 8.1 or 10 until last week

    I mean it is just old.

    It doesn't have to occur immediately.

    Thanks

    If its ok with you I would like to leave this unanswered for a few days just so I can monitor the issue

    might not be much that can fix it if the driver is old and the fault remains, but just want to see if its now resolved

    I recommend it to leave a thread open for a few days in case any BSOD occurs

    Good Morning

    Not urgent for checking, but if you have a spare few mins can you have a look to see if this is the same issue
    I didn't notice the blue screen (might have been there when I wasn't looking though), I just heard the computer restart at 11:57pm yesterday and after restarting it had changed the driver for the tuner again

    Thanks

    Please check the details of the driver cydtv.sys
    Located at C:\Windows\system32\drivers\
    I just want to make sure we have the right software that causes this
    Code:
    1: kd> lmvm cydtv
    start             end                 module name
    fffff801`52340000 fffff801`523f9d00   cydtv    T (no symbols)           
        Loaded symbol image file: cydtv.sys
        Image path: \SystemRoot\system32\drivers\cydtv.sys
        Image name: cydtv.sys
