looks like all of your motherboard drivers are really out of date (2010 and 2011)
you have a updated BIOS and must update the motherboard drivers to match or you can have various problems.

(confirm it is the correct board and version of the motherboard, looks like motherboard rev 1.0)
the BIOS you have installed has a BIOS fix for audio, so you should install the updated audio drivers for the motherboard.
---------
based on the date of the audio driver, I would guess it just has a bug, look for a update.
\SystemRoot\system32\drivers\cmudaxp.sys Wed Mar 09 23:44:15 2011
you should also update your xbox driver:
xusb21.sys (this one causes memory corruption that was fixed in xusb22.sys driver)
------------------
first bugcheck looks like a corrupted stack in cmudaxp.sys
audio driver:
http://www.carrona.org/drivers/driver.php?id=cmudaxp.sys
it looks like something overwrote the stack with data and one of the date values was zero, then the system executed it
it called a bugcheck.
I looked at the stack to see if there was another driver storing its data next to the audio driver. there was not. just other calls by the audio driver.
I think it corrupted its own stack.
the stack contained audio code, some directx code and what looks like amd graphic code. (atikmdag.sys and atikmpag.sys)
maybe your sound support for your graphic driver is conflicting with your audio driver.
you might want to go to windows control panel and disable any high definition sound driver that you are not using. video GPU sound support if you don't have a speaker in a monitor getting sound from a video cable
