Hi,
the above dump file can be caused by either faulty device drivers or system software, Bios incompatibilities, memory conflicts as well as IRQ conflicts. It seems that data placed in the memory couldn't be read for some reason.
Checking through the dump file I see your Bios is out of date and this could well be linked with the above error:
BiosVersion = P2.00
BiosReleaseDate = 07/13/2012
Current Bios release stands at 2.90 and includes increased functionality and stability:
(Please ensure you have the correct download for your system)

asmthub3.sys Fri Mar 04 07:55:10 2011: ASMedia ASM1042 USB 3.0 Hub driver. Please update:

asahci64.sys Wed Sep 21 10:42:57 2011: Asmedia 106x SATA Host Controller Driver please update:
http://www.station-drivers.com/inde...roller-Drivers-Version-2.0.9.0001-2.0.3.0002/

Please run the Intel update utility:

Your also missing a Realtek Hi-Def Audio driver:

As the GPU driver is mentioned in the dump file try updating to the latest beta but use this app to remove your old driver:

AMD:

Try running the system file checker to make you have no corruption in the system. Find command prompt in the start menu, right click on it, choose properties and then run as admin. Type:
sfc /scannow
Press enter and await results.

If after making the above changes you still get the bsod then you need to test your RAM.
Windows does have it's own memory testing app but it can often miss errors and the best app for the job is Memtest86. The latest version of which can be found here:
http://www.memtest.org/

To run Memtest86 you need to either burn a copy of it to disk or use a USB stick. If you look down the page you'll eventually find the latest version and it's associated downloads. If your burning to disk choose the pre-compiled iso zip. If your using a USB method then the corresponding download is the auto installer for a USB stick.
Once you have Memtest86 on the media you selected you'll then need to enter your bios and change the boot order so that the machine will boot from either the disk or stick you have Memtest86 on.
Try and run the test overnight if possible unless it becomes clear that there is a issue. If there is a problem with the RAM you'll see the errors pop up in red so you can't miss them.

Post any new dump files.
