All 4 BSOD's point to atikmdag.sys - a component of your ATI graphics (video) drivers
Please do the following:
- download a fresh copy of the latest version of the video drivers for your system from the ATI website.
Do not download the entire Catalyst Control Center (I've seen issues with this), rather download the driver only (usually lower down on the page).
- uninstall the current version of all ATI stuff from your system
- install the freshly downloaded version
- check to see if you have any further BSOD's
Additionally, please update all of the Asus programs/utilities that you have installed on your system. Here's a list of all the older drivers that were loaded when the system experienced the last crash - please update them:
