The Desktop Window Manager has encountered a fatal error (0x8898009b) - Windows 7 pro
Aero is fine - very smooth etc, and generally works fine until the machine goes to sleep.
Anyone else run into this? What is the solution?

No thanks to either Microsoft or HP but I have finally found a fix for this issue. It may only be a workaround but it certainly works for me.
Some system boards may be able to fix this with BIOS, if you are unable to fix in BIOS, then you can try the following Windows 7 workaround.
1. Start, type cmd, right click, Run as Administrator.
2. Type bcdedit /set useplatformclock true and press enter.
3. Type bcdedit /enum and press enter.
4. Verify that useplatformclock is on/true.
5. Restart the computer then test your sleep/aero/WMP issues.
The above worked liked a charm for me on the following platform:
System Manufacturer HP-Pavilion
System Model FQ563AA-A2L a6750f
Processor AMD Phenom(tm) 9650 Quad-Core Processor, 2300 Mhz
BIOS Version/Date Phoenix Technologies, LTD 5.13, 07/05/2009

Windows 7 Home Premium 64 Bit
HP M9500m with MSI Nvidia 8400 GS Video card
IE 11 will Freeze Up and the completely Lock Up after Windows Wakes from Sleep Mode
Event Error log:
The Desktop Window Manager has encountered a fatal error (0x8898009b)
I haven't figured out what the problem is but I think it's related to one of Windows Update Patch.
First I reinstalled Windows 7 64 bit Homed ED and all the Windows Updates and Drivers Updates.
Same Problem.
Then I Formatted and Clean installed Windows 7 without any New Updates. No Problem with
Waking Up from Sleep Mode.
IE 8 works fine.
I've Reinstalled my previous Window 7 Image File and will remove each of the updated Microsoft patches
I am determined to find out which of the updates is giving me all this grief.

I see that this is very big problem, and it was for me too, until I restored my overclock. Couldnt belive my eyes, I mean what do this have to do with overclock.
I overclock my NB and HT by 200mhz, and overclocked the ram, lowered the timings. Maybe its because of ram i dont know, but it helped. Aero is working now, I have all visual settings, WEi is working, no more Event 9020 Desktop Window Manager error. Everything is as it should be.
I hope this helps someone.
