Windows 7: Reliability Monitor Wont Display Graph

01 Nov 2009   #1

Windows 7 Ultimate (x86)
Reliability Monitor Wont Display Graph

Im having a really tough to TS problem with the reliability monitor. For the last week, it no longer displays any data and the graph dosent render.

It just display as blank with no data. Some things to note...

1. The RAC published and State data are being updated and published each day as they shouold. So the data does exist.
2. I have tried the "Resetting RAC" methods that worked for Vista. But the fix dosent work for W7.
3. I cant think of anything that may have changed. I havent deleted any folders or log files.
4. I've used Process Monitor to trace the events when the reliability monitor executes and everything looks fine.
5. There are no errors or warnings in the event viewer.
6. I havent installed any Windows Updates.

So Im hoping that someone can think of something I am missing here. Oddly it used to work for some time and i ran it each day. Then all of a sudden one day it just stopped.

Could this be a permission issue possibly? I do recall changing permissions for C:\Users\Me\AppData. Are there any folders or logs within that path that might affect RAC? Are there any services that are required for RAC to collect and render data?

Any ideas would be greatly appreciated.

You're not a "registry cleaner" (ab)user, are you?

Does the same symptom occur in safe mode?

Is the wmimgmt service running? Stoppable? Restartable?

As a wild stab in the dark, one of the standard causes is the loss of COM registrations from components used in rendering that info. If you haven't already tried all that, do a web search on regsvr32 and "reliability monitor" for a list of DLLs worth re-registering.

I dont do any real registry cleaning. Only removing obsolete keys under HKCU\Software after I've uninstalled an application.

I think your on to something in that it could be a service thats not running. Here is what I noticed for services set to manual...

Performance logs and alerts
Problem reports and solutions
WMI Performance Adapter

WMI is set to Auto and running. Thanks BTW for the tips.
