Windows 7: Random BSOD while surfing on Chrome

04 May 2015   #1

Random BSOD while surfing on Chrome

Hi people, this is my first time posting here.

For the past 2 days, I been surfing the web and watching Youtube videos and suddenly I get BSOD out of nowhere. It only started 2 days ago and I just got one BSOD of the same issue about 1 hours ago.

I have downloaded BlueScreenView and paste the following text it provided me below. I have also attached the dmp file in this post.

My desktop is custom built and it is fairly new so I think it should not be the issue with the hardware.

The only driver I may have installed the past few day would be my brother's flash drive.

Kindly help me with this issue

That zip does not contain all the necessary information.

OK, you try SF Diag tool and upload the resulting zip with your reply post.

If further data is required, upload it with your reply post only, dont alter the original post.

The crash dump blames Qualcomm Atheros Bandwidth Control, a component of Killer Network Manager. It is set to auto start with windows.

Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.
  1. Click on the Start button
  2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
  3. Select the “Startup” tab.
  4. Deselect all items other than the antivirus.
  5. Apply > OK
  6. Accept then restart.
BTW, you have Daemon Tools there. Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from, and execute the downloaded file as guided below :
  • Double click to open it.
  • Click this button only:
  • If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.
Report us for any further BSOD after doing these.

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
