📎 AI Summary:
The thread discusses a persistent BSOD issue on a Windows system, primarily caused by the driver dvb7700all.sys, associated with a YUAN DVB-T/Analog Hybrid TV Tuner. Despite attempts to update the driver and verify system integrity, the problem persists, with the BSOD linked to usbhub.sys and power-down events. The main recommendation is to remove or update the problematic driver and check for a newer version to resolve the crashes.

Could you please someone help me with this problem:

Unable to load image \SystemRoot\System32\Drivers\dvb7700all.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for dvb7700all.sys
*** ERROR: Module load completed but symbols could not be loaded for dvb7700all.sys

Typically all your driver (.sys files) are located here
C:\Windows\System32\Drivers
So if you have identified the Driver Name and are showing file extensions then you should be able to simply rename the driver from dvb7700all.sys to dvb7700all.OLD.
This technique should effectively break the driver and prevent it from loading on the next reboot.
If that is or was in fact the cause of your Blue Screens then you should be able to tell soon enough and if not the process is easily reversed by simply renaming it back to dvb7700all.sys

Yes.. If you look at Port 2 you can see the Hybrid Tuner. Just right click on it, hit properties and then remove the driver. I'd leave the chipset drivers on as they are used by a multitude of things.

Until today everything seems to work five. Problem with BSOD solved. Will this change to .OLD effect any updates in the future?

Now, when I open the device manager I can see the driver. Should I uninstall it from here?

To be honest if your machine is running bsod free I'd be tempted to leave it where it is. However if you really do want to remove it then it shouldn't be an issue to remove it via the device manager.
