NOTE1:Link thanks to blueelvis (15Oct2014):
https://forum-en.msi.com/index.php?topic=178064.0 This is a method for removing all the network software and only installing the driver. Perfect for those issues that can't be resolved any other way!
NOTE2: See this link first:
BSOD while playing on msi gt70 dragon edition 2 (thanks to kaelaan) It appears that the Killer Service problem was solved with the latest release of the Qualcomm versions of the drivers (so try updating to a version dated from later in 2014).
The Qualcomm Atheros Killer Service/KillerNetManager is known to cause BSOD's. Please follow the workaround instructions here:
First, open the Run dialog (Win + R keys) and type in "services.msc" (without the quotes) and press Enter
Scroll down and locate the "Qualcomm Atheros Killer Service" and right click on it. Select "Stop"
Right click on it again and this time select "Properties"
In the dropdown box for "Startup type", select "Disabled", then click on the "OK" button at the bottom of the window
Next, open Task Manager (right click on TaskBar and select "Task Manager")
Click on the "More details" dropdown (if present)
Click on the "Startup" tab
Scroll down and locate the "KillerNetManager" entry, right click on it and select "Disable"
There may also be an Install Shield (with the Killer gaming K next to it), if so Right click on it and select "Disable"
Finally, restart the system in order for the changes to take affect.
At times the Killer Network Manager will continue to load. If so, it's usually listed in the MSINFO32...Software Environment...Startup Programs section. If it is, please try this:
It may be that the instructions aren't stopping everything.
In some cases, there's a program running out of the Program Files/Program Files (x86) directory.
"c:\program files\qualcomm atheros\killer network manager\killer~1.exe" (NOTE: killer~1.exe is most likely killernetmanager.exe)
In other cases, there's a program running out of c:\windows\installer\{Long string of letters, numbers, and dashes}\networkmanager.exe_130c27d738f34c89bddf21bcfd74b56d.exe (the long string of letters and numbers may change)
Here's some things to try
1) Please see if there are any entries in the Startup tab of Task Manager that are related to Qualcomm/Atheros/Killer Network Manager (and NOT the card itself) and disable them (please let us know what you find) Be careful as the wrong selection can disable the network card.
2) Check in "msconfig" for any entries that aren't in the Startup tab of Task Manager. Let us know if you find any Qualcomm/Atheros/Killer entries there (we'll disable them differently if they are there).
3) Locate the "c:\program files\qualcomm atheros\killer network manager\killer~1.exe" and rename the .exe to .BAD (the killer~1 is actually a filename that starts with killer and ends with .exe) There will be an error in event viewer, but it'll stop the bugger from loading.
4) Locate the "c:\windows\installer\{Long string of letters, numbers, and dashes}\networkmanager.exe_130c27d738f34c89bddf21bcfd74b56d.exe" entry and rename the last .exe to .BAD (the long string of letters and numbers may change)
