The information in the dump is not the system according to the profile (right pane). The dump stack show only atikmdag.sys hence the main culprit at this point, especially with the first argument "C0000005", this is a memory access violation, the ATI driver attempt to access an out-of-bound memory Noticed you are running FlashPlayer when the system crash, update Flashplayer as well to narrow the problem.
The ATI driver is updated recently in 12 August, if the problem arise after this update, uninstall it then reinstall the previous version.
