Hi, your mini-dump appears to be pointing at the driver file:
atikmdag.sys which is your ATI Videocard driver:
Driver Reference Table
Please un-install your graphics card driver from Control Panel/Add-Remove a Program first. Then please install Driver Fusion to remove all traces of the driver (usually AMD/Display). You may have to use Driver Fusion twice or more after rebooting in order to remove everything if you're using the trial version:
Driver Fusion - The Complete Driver Solution
Then please download and install the latest version of the drivers from this site using the "autodetect" tool:
AMD Driver Autodetect
You also have some out-of-date drivers on your system which can cause the BSODs. Please update these drivers to the Windows 8 64bit verisons or un-install/remove them if un-needed:
AsUpIO.sys - ASUS hardware monitoring software related:
Driver Reference Table (please un-install ASUS Utilities Suite, known to cause BSODs on some systems)
ASUSFILTER.sys - ASUS USB Hub filter driver:
Driver Reference Table
ICCWDT.sys - Intel(R) Watchdog Timer Driver:
Driver Reference Table
ElbyCDIO.sys - CDRTools/ElbyCDIO/DVD Region Killer/VirtualCloneDrive (elby CloneDVD™ 2)/AnyDVD:
Driver Reference Table (please un-install any of these programs for testing purposes, known to cause BSODs on some systems)
emusba10.sys - E-MU USB-Audio 1.0 Driver:
Driver Reference Table (this is a very old driver from 2007, you should try updating it to Windows 8 64bit versions or un-intsalling)
Please download Windows 8 64bit drivers from your motherboard manufacturers website. Please update chipset and anything else you feel might need updating:
ASUS - Motherboards- ASUS P8Z77-V DELUXE
Please make sure you have all the Windows 8 updates if you have not done so already.
-cheers
