An analysis of these minidump files indicate a consistant issue with both the graphics (ATI) display drivers and DirectX. You should make an effort to completely ensure that your video graphics card drivers are up-to-date and that the physical device is seated properly with enough power going to the graphics card.
If you continue to experience this problem, I would recommend performing a full audit of all graphics related hardware and software on your system.
Basically, the kernel of the system is faulting, according to the BSOD read-out. During most of these failures, we are seeing a
PAGE_FAULT_IN_NON_PAGED_AREA and
IRQL_NOT_LESS_THAN_EQUAL involving
dxgmms1.sys,
atikmdag.sys,
ntoskrnl.exe, usbport.sys, hal.dll.
Here is what this tells us:
- The NT kernel is crashing. This results in the blue screen.
- Memory allocation errors are occurring that could be related to graphics hardware or drivers.
- In at least one specific instance, Catalyst Control Center (CCC) drivers are involved in the crash.
- In at least another specific instance, the USB port control driver is related in the crash.
- There is evidence DirectX errors are causing the system failures, but this would mostly be related to your video graphics card and not necessarily DirectX itself.
This makes sense in the fact that the system is crashing while you are playing games. If you are using a USB device while in the game, such as a gamepad, this would explain why the USB driver appears in the crash at least once.
Recommended solution:
Check some information regarding the files listed above. Some claim they have found a solution to the problem in some instances.
Use
Link Removed - Invalid URL (SFC /scannow) to ensure that the problem is not related to corrupt system files.
Completely uninstall all ATI related drivers properly
using the methods listed here.
Re-install the latest drivers using the above listed methods.
My AMD/ATI Radeon HD 6850 card is running at 45 C on idle. If you are tasking your set up, you may in fact go up to 60 C, but not on idle. If you continue to experience these errors, you should check the seating of the physical card, remove all unnecessary devices from the system, consider checking for additional driver updates. But, all indications seem to reveal a problem, not with the memory itself, but with the allocation of memory when the video card is in use. This would be indicative of a problem with the graphics hardware.
Of course, one way to determine if your graphics card is at fault would be to swap it out with another, or test the existing graphics card on a different computer. Since this is very likely to be impossible, you should use the above steps to come to your own conclusion. However, I would suspect that video card could be at fault in this instance.
