This is bugcheck is a bugcheck code of ATI drivers. As we can also see that the
ATIKmdag.sys calls the bugcheck and hence the culprit.
Now the following reasons could cause this problem :-
1. Somehow your ATI drivers are corrupt. So please completely uninstall the Amd Catalyst Control Centre and install only the Display driver to see if the problem still persists or not. In case the problem is still there, check whether the problem existed in the driver some versions before?
2. You may have faulty RAM. Please download this tool and run it atleast for overnight.
Memtest86+ - Advanced Memory Diagnostic Tool
3. There is a loose port or cable which is causing this problem.
4. It is also possible that the PSU is not able to give enough juice to the GPU.
5. There is hardware problem with the Graphic Card.
Please first test out the 1st and 2nd steps before proceeding further and make sure to keep the updates posted here ^_^.
