Daemon Tools (and Alcohol % software) are known to cause BSOD's on some Win7 systems (mostly due to the sptd.sys driver, although we have seen dtsoftbus01.sys blamed on several occasions). Please uninstall Daemon Tools.

As an alternative, many people recommend the use of Total Mounter or Magic ISO

AVG is a frequent cause of BSOD's. Replace with Microsoft Security Essentials & the Free version of Malwarebytes, update and make full scans separately:

Malwarebytes Free

  • Pay close attention to part 3 of the tutorial "If you have errors"
  • Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.
