| Event Information | According to Microsoft :
Cause :
This computer does not have adequate system resources
Resolution :
Make more resources available on the system
During Windows logon, the operating system opens the subscriber notification database and starts the user-level processes so that user accounts can log on to the system. If there are inadequate system resources for Windows logon to do this, the system may start with limited functionality.
To identify the applications or services that are using too many system resources, you can generate a System Diagnostics report by using the Reliability and Performance Monitor.
To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.
To make more resources available on the system:- Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
- Type perfmon /report and press ENTER. The Reliability and Performance Monitor will start collecting data to create the System Diagnostics report.
- When the report is ready for viewing, locate the Diagnostic Results section of the report, and check for any Warnings. You can follow links to additional help on resolving warnings from this section. In addition, you can expand each category in the Basic System Checks section to see more details about why warnings appear.The Performance section of the report provides process-level detail about applications or services that are using the most resources.
- Identify the applications or services that are not required.
- Click Start, and type msconfig.exe to open System Configuration. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
- Click the Service tab, clear the check box next to the names of the services that you want to disable, and then click Apply. If you do not know which services you require at startup, note the services that are currently configured to start and then click Disable all to disable all services.
- Click the Startup tab, clear the check box next to the names of the programs that you want to disable, and then click OK. If you do not know which programs you require at startup, note the programs that are currently configured to start and then click Disable all to disable all programs.
- Restart the computer.
Cause :
This computer has a corrupted registry
Resolution :
Repair a corrupted registry
During Windows logon, the operating system opens the registry and reads the list of user accounts that are configured for the computer. If that data cannot be read, the Windows logon screen is not displayed and users will be unable to log on to Windows. Whether or not Windows will be able to complete the startup process depends on the severity of the registry corruption.
If the Windows registry is slightly or moderately corrupted, you may be able to restart the computer in Safe mode and use System Restore to restore the registry of the computer to the last known good configuration. However, if the Windows registry is severely corrupted, all types of logon will be prevented. Attempting to log on to Windows causes the system to fail and then to restart. In this situation, you will need to boot the system into the Recovery Console instead of into Windows. Once in the Recovery Console, you can use the Startup Repair tool. Startup Repair automates common diagnostic and repair tasks of unbootable Windows installations.
To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.
