BSOD - possibly related to dota 2

Sorry about the vagueness of the title, dota 2 had been open in at least 2 of the last 3 incidences (all happened within two days).

Thank you for taking the time to read this.

Welcome to SevenForums.

The BSOD seem to be caused due to network errors.

Code:

Please uninstall Alcohol. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7. Uninstall the software using Add/Remove Programs. Reboot the system. Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

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

You also need to update your video card drivers:

Code:

lmvm nvlddmkm
start             end                 module name
