Windows 7: BSOD during normal activity on Toshiba Laptop, log uploaded

BSOD during normal activity on Toshiba Laptop, log uploaded

For the past couple of days, I've been receiving BSOD errors. I happened to notice this is occurring after the latest round of Windows Updates, but I don't know that it's at all related. Any help would be greatly appreciated.

Welcome to the forum.

 Clean boot
Reduce items at start-up. No software except anti-virus is required plus doing this improves the time for logging into windows:
Caused by Atheros NIC driver Driver Reference Table

Update it to the latest version available.

Sometimes drivers remain and do not get completely uninstalled.

 Driver Removal Process:

  • Download Driver Sweeper to the desired location.
  • Extract the files from the zip.
  • Uninstall the driver Program & Features - Control Panel.
  • Run Driver Sweeper, check the drivers you want to uninstall or clean registry leftovers of.
