Hi SHALRKSTER

Tour minidump files indicate a driver named AsIO3.sys is causing the crashes, not much is known about that driver, it seems to exist on Asus systems

If you have an Asus system do you have Armoury Crate and/or Aura installed on your system?

 

BSOD while using the internet. error (L1C63x64.sys)


Hi trainman81,

Welcome to the 10forums.

Daemon tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known cause for BSOD's.
Please remove Daemon Tools and run the SPTD pass through remover.

1. Uninstall Daemon Tools
2. Download the SPTD standalone installer and follow these steps:
   • Double click the executable to open it
   • Click on the button shown below

If the button is grayed out, like in the image, there is no more SPTD installation on your system, and you can close the window


AVG is trying to request data from the internet, which is why the network driver is marked as the cause.

Hi 大伟王2

Your minidump files indicate the following two drivers as a cause of the crashes:

AsIO3.sys - This seems to be part of the Asus Armoury Crate utility

igdkmdn64.sys - Intel Graphics device driver.

Go to the support page for your PC on the manufacturers website, then from there, download and re-install the Armoury Crate software and Intel graphics device drivers they recommend.
