0x3b Bsods when playing full screen games

Hello,

Code:

OS Version:                6.1.7600 N/A Build 7600

You're missing Service Pack 1, highly suggested that you install this as it secures the PC and fixes a whole lot of problems.
You can download through either Windows Update, or download from here Download Windows 7 and Windows Server 2008 R2 Service Pack 1 (KB976932) from Official Microsoft Download Center

This could be the main cause of the BSOD, but here's some suggestions:

Code:

dtsoftbus01.sys             Fri Feb 21 03:49:36 2014 (53072130)

This driver belongs to Daemon Tools, known problem with Windows. Please uninstall.


On a side note:

Having a cracked version of Windows can also cause some errors. I highly suggest you purchase a legit version, and work from there also.
