BSOD Bad_pool_caller on Switching Users (Windows 7 Ultimate x64)

GbbG asked on

Greetings!

I have been getting a BSOD whenever I switch users on my laptop running Windows 7 Ultimate (x64 w/all updates).

I am attaching the minidump files here: http://1drv.ms/1fvMY61

Error as seen in EventViewer: 

Fault bucket , type 0
Event Name: BlueScreen

I am not sure what's going on. The only drivers that aren't "official" sony vaio ones are the nvidia graphics card drivers.

Hi,

The latest attached DMP file is of the BAD_POOL_CALLER (c2) bug check.

This indicates that the current thread is making a bad pool request.

^^ Dated circa 2012, evidently however there's no update.

Uninstall the NetGear USB Control Center as it's known to cause this issue.
