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.
