*original title - Misc tasks running, screen freezes, video driver unloads (GPU fan defaults to 100% speed) and then BSOD atikmpag.sys - 3 months of pain*
Okay, this is going to be long and drawn out, so let me start with my sincere apologies.
Description of the issue:
I rebuilt my entire machine a couple months ago, after purchasing a TechNet Plus subscription, new ATI Radeon 5870 2GB video card, and new AMD PhenomII X4 965 CPU. I promptly installed Windows 7 Ultimate x64 and started loading all up-to-date drivers and applications. Then, the problems began. I would be playing WoW and the game would freeze, the screen would turn gray, then black, then the fan on the video card would spin up to 100% throttle (Windows unloaded the video driver), then about 60-90 seconds later, I would get a BSOD with either atikmdag.sys or lately it has been atikmpag.sys. This would also happen while watching video clips in either Windows Media Player or VLC, and sometimes even when watching YouTube videos (both in IE or Firefox).

Attempts at resolution:
1. Reinstalled Windows 7
2. Reinstalled Windows 7
3. Took system to local computer shop and received a replacement video card from stock
4. Reinstalled Windows 7
(while reinstalling Windows, attempted to use ATI Catalyst Drivers version 9.12 (from original CD), 10.1, 10.2, 10.3, 10.4, and finally 10.5 installed on 6/3/2010)
5. Attempted changing ATI Performance Profiles XML
Changed CoreClockTarget and MemoryClockTarget for Want_0 and Want_1 to be higher than
default, so the card would not have to increase speeds as much (recommended via ATI
**started happening like clockwork when I installed RollerCoasterTycoon3, crash guaranteed within 30 minutes of starting a scenario, this began on 6/1, so the following entires are from this past weekend to today**
New Drivers from ATI, 10.5, installed. No change in behavior.
6. Disabled Aero within Windows (no effect, re-enabled)
7. Uninstalled Catalyst Suite, leaving bare drivers only (current config with version 10.5)
8. Attempted to use verifier.exe to diagnose the issue, system would only BSOD while booting, very soon into the splash screen, then reboot
9. Attempted Window Repair, unable to find a solution, no changes, rebooted
10. Booted Safe Mode in order to execute verifier.exe and remove current running values
11. Rebooted Windows normally
12. Called Microsoft Support (Case number available upon request by PM) 6/7/2010
Microsoft Support technician controlled my computer for a few minutes, and I showed him the minidump file using dumpchk.exe, but he said that it looks to be just a video card driver issue. I have a very very difficult time believing that after 3 re-installs
and 5 different versions of the drivers. I am going to attempt to contact ATI support tomorrow. I figured that someone on this site might be able to assist me with analysis of the minidumps and possibly find the real root cause of this issue. I am going
to upload DxDiag.txt output, the minidumps, and the full memory.dmp file (compressed with winrar on best setting, but still had to split into two files because of the 50MB restriction) to my skydrive public folder, linked below:
If there are any items that I have left out, or questions, please ask and I will answer as quickly as I possibly can. I really want to resolve this issue so I won't have to format and downgrade to a different OS.
