BugCheck 3B, {c0000005, fffff80001aa947b, fffff8800bab8d00, 0}

Probably caused by : ntkrnlmp.exe ( nt!ExQueryPoolUsage+e0 )

The above bugcheck can often appear for a number of reasons:
A process within Windows is corrupt, out of date drivers/bios and/or bad RAM modules. I know your system is brand new but it's not unknown for brand new RAM to have faults.
Pacer.sys is a Windows driver and part of the network so either that driver or data within windows is corrupt or something else is causing Pacer.sys to crash. Looking through the dump file for clues is the best way to go and the more you have the better. As we have only one I'll try and cover a broad range of possibilities although we usually do this anyway unless it's something very obvious.

Update Bios:
BiosVersion = P1.00
BiosReleaseDate = 04/28/2014
BaseBoardManufacturer = ASRock
BaseBoardProduct = Z97 Killer
There has been several updates since the board (very nice board by the way) was released. You'll need a USB stick which you'll have to format so it's FAT32 on which you'll store the new bios download on. Just follow the instructions given on the web page under the red plus sign: Z97 Killer/?cat=Download&os=BIOS

Norton AV:
I see your running Norton AV. Norton is well known in debugging circles for causing issues and sadly it's not the app it once was circa 2002. Please uninstall using this tool:
Please use MSE as it's extremely stable:

athrx.sys Wed Feb 22 06:29:09 2012: Atheros network adapter driver please update using download off MoBo website: Z97 Killer/?cat=Download&os=Win764
In fact please go through the above webpage and apply all those latest drivers as I see your missing at least one.

Windows corruption
To ensure Windows is corrupt please run the System file checker. To do this look for command prompt in the start menu, right click on it and run as admin. Type:
sfc /scannow
Press enter and await results.

If after completing the above changes your still getting a bsod then download the latest version of Memtest86 here:
This guide although a little old explains how best to use it:
