BSOD - every restart - bcmlw6.sys

One of my laptops, recently updated to windows 10, gives a BSOD every time it is restart. The error message is system_thread_exception_not_handled bcmlw6.sys

Any ideas on how I might fix this?

If the computer is shut down it doesn't happen - it only happens during a restart. It never happened with Windows 7.

Thanks in advance for your help!

Hi Azucho98,

Welcome to the 10forums.

I recommend to update your BIOS

Code:

BIOS Version:              Hewlett-Packard F.22     , 3/23/2006

Z97-DELUXE | Moederbord | ASUS Nederland

Attachment 47601

The broadcom driver has been flagged

More likely than not due to your wireless drivers... especially if using a broadcom/dell wireless card, as they included windows 8 dll and sys files in their win 10 driver package for broadcom ac wifi cards. This resulted in BSOD loops occurring every 15 - 60 min on a system with the Windows 10 drivers installed.

If you upgraded your computers to Windows 10 and did not clean install afterwards, it's recommended to clean install as many drivers and driver installed system files from the previous OS are copied to the new Windows folder. Windows 8/8.1 drivers are not compatible with Windows 10 in any way [the only exception being CPU chipset drivers).

As axe0 mentioned in their post, the BIOS/UEFI firmware must be kept up to date and not doing so can lead to abnormal and anomalous issues. It's a good habit to get into to check for BIOS/UEFI firmware updates and driver updates once a month. BIOS/UEFI firmware updates are generally only pushed out a few times a year at most, however incorporating the check into your monthly driver check serves the purpose of two birds, one stone.

• For users that bought their device pre-assembled from an OEM, it's as easy as checking the support site for your device.
• For users that built their own rig, creating a bookmark folder and saving all driver pages for your hardware in it would be just as convenient. This would allow you to right click the folder and select to open all pages contained within.

Just an FYI: I personally am a bit tired of seeing post after post stating how users never had this problem or that problem with Windows 7:

• The majority of issues most users are experiencing have zero to do with Windows 10 and everything to do with third party drivers and software. In addition, comparing the two OSes is apples to oranges.
  
  • It is the responsibility of the end user to ensure the third party drivers and software they install are fully compatible with Windows 10 (or any new OS they choose to upgrade to).
  • In regards to software, it's especially important to guarantee system critical software, such as Internet Security software [antivirus, malware, stateful firewalls], are fully compatible with Windows 10 prior to installing.
  
  
• When clean installing, there is a specified order in which system drivers must be reinstalled [prior​ to running Windows Update​] and no deviations can occur for the first 5 drivers (deviations will most likely result in wonkiness occurring at some point in the future):
  
  1. ​Chipset Driver
     
     • regardless of what OS they were built originally built for, these must always be installed, and installed first
     
     
  2. IMEI & other CPU related Drivers
  3. RST Drivers (if you have Integrated Graphics, RST drivers must be installed even if you don't use a RAID config)
  4. Integrated Graphics Drivers (CPU)
  5. Discrete Graphics Drivers (GPU)

I find that too a little annoying, but they forget Windows 7 and Windows 10 are different systems.

Back on-topic: @Azucho98, please let me know how it goes :)
