I am coming to Windows 7 from Vista 64bit Ultimate. On Vista I was able to get aero enabled and my system scored a 4.7 on the winsat tests. When I did a clean install and went to Windows 7 Ultimate 64bit, my aero doesn't want to initiate. I also cannot complete my winsat test because when it gets to hard disk it says could not measure storage performance. I put in the latest drivers form nvidia's website and I got aero for a few seconds at start up only for it to change back to basic. I have tried forcing aero with those registry edits. I have also tried the troubleshooting transparency and aero effects and it gives me aero for a sec then goes back to basic. The problem it lists is the Desktop Windows Manager to be disabled. I have tried stopping and restarting the Desktop Windows Manager but it only does the same thing as the troubleshooter. I have also tried putting it to high performance in power options and setting it to best visuals but no dice. My system: XPS 200 w/ pentium D 2.8ghz with an upgraded 9500GT and 2GB RAM This was just cleanly installed so application compatibility problems is not likely. I have done all windows updates. Thanks for reading! The help is greatly appreciated!
smells like a gpu drivers conflict. dell doesnt have windows 7 drivers for your gpu-system? if yes use those and not the windows update ones. in any case clean display drivers and try once with dell-nvidia drivers and once with windows update drivers. dont forget to clean registry after every uninstall using apps like ccleaner and 1 click cleaner of windows 7 manager
No, this is a 5 year old machine with an upgraded graphics card. It originally came with a POS X600 I believe. The drivers I am using are straight from Nvidia's website and the latest ones. I don't have many apps at the moment since I just clean installed and this occurred straight after I got to the the desktop for the first time. I looked at Event Viewer and saw this: Log Name: Application Source: Desktop Window Manager Date: 8/20/2010 5:39:01 PM Event ID: 9020 Task Category: None Level: Error Keywords: Classic User: N/A Computer: Description: The Desktop Window Manager has encountered a fatal error (0x8898009b) Event Xml: <Event xmlns="htt p://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Desktop Window Manager" /> <EventID Qualifiers="49152">9020</EventID> <Level>2</Level> <Task>0</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2010-08-20T21:39:01.000000000Z" /> <EventRecordID>1113</EventRecordID> <Channel>Application</Channel> <Computer></Computer> <Security /> </System> <EventData> <Data>0x8898009b</Data> </EventData> </Event> then this Log Name: Application Source: Desktop Window Manager Date: 8/20/2010 5:39:02 PM Event ID: 9009 Task Category: None Level: Information Keywords: Classic User: N/A Computer: Description: The Desktop Window Manager has exited with code (0x8898009b) Event Xml: <Event xmlns="htt p://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Desktop Window Manager" /> <EventID Qualifiers="16384">9009</EventID> <Level>4</Level> <Task>0</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2010-08-20T21:39:02.000000000Z" /> <EventRecordID>1114</EventRecordID> <Channel>Application</Channel> <Computer></Computer> <Security /> </System> <EventData> <Data>0x8898009b</Data> </EventData> </Event> (Took out pc name and had to make a space in http because my post count is not high enough) and looking at the service in services it is set that if it fails to restart and do this the second time also then if it happens a third time to do nothing. So what happens is for some reason it fails and gets restarted giving me basic for a split second then going back to aero then doing the same thing then stopping and staying in basic mode until I start the system again.
copied from another forum ...... hi all, had the same exact problem with Aero starting running for a second then screen flashed and service quit with error (0x8898009b) and then of couse is not running so aero troubleshooter thinking dwm is disabled but its not. Microsoft put out a statement that after looking at the issue it is caused by a glitch between windows 7 OS and some manufacturers motherboards with nvidia/ati chipset and have S3 power management. SO ... What I did to fix it : Disable windows desktop manager service Restart BIOS --> change power management so that S3 is DISABLED! Only allow S1 (POS) power mode or all OFF Restart Windows loads and ACPI notices hardware changes, allow reboot Restart Start up cmd.exe as Administrator and type in the following sc config uxsms start= auto net start uxsms BINGO --> aero is running and stable should never halt now.. this problem is rife on the internet affecting many computers ,you only have to google that error code to find out .the above method is supposed to work OK according to a few . good luck.
I actually saw that on another forum and gave it a try and it didn't work. I put it to S1 since my bios doesn't allow to me shut it off completely. I have reinstalled Windows many times because of this and the same issue occurs. Maybe I need to get a Windows 7 compatible BIOS made for my machine? That's the only thing I can think of.
I called EVGA and they said it could be a BIOS or north/southbridge incompatibility issue. It seems plausible to me. Although after I installed some file from Intel's website for the 945g chispet, it takes longer for aero to crash.
