Periodic BSOD while going to "sleep" ntoskrnl.exe + 10f6b 0x0000009f

Firstly, I would like to apologize for my bad English

After updating some drivers and install some software I get time to time BSOD error while I put Windows in sleep mode...

Update the network driver form Realtek .... Get the second one of the list, i.e. the Win7 and Server 2008 R2 Auto Installation Program one and install it following the instructions supplied inside the zip.

Also update the driver to the webcam ..... HD Webcam C270

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.
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.
Report us for any further BSOD after doing these.
