Starts Windows in its normal mode. Windows 7 More The diagnostic startup option enables Windows to determine which basic device drivers and software to load when you start Windows. When you use this option, the system temporarily disables Microsoft services such as the following services:. If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
On the General tab, click Diagnostic startup , and then click OK. If the issue does not occur after Windows restarts, use the selective startup option to try to find the issue by disabling and enabling individual services and startup programs. The selective startup option enables you to select the programs and services that you want the computer to load when you restart the computer. You can select from the following options:. When you click to clear the Load system services check box, you disable Microsoft services such as the following services:.
On the General tab, click Selective startup , and then click to clear the Load system services and Load startup items check boxes. If you can reproduce the issue after the computer restarts, the issue is not related to system services or startup items. In this case, the System Configuration utility will not help troubleshoot the issue. If you cannot reproduce the issue after the computer restarts, the issue is related to either the system services or the startup items. To determine the items to which the issue is related, follow these steps:.
On the General tab, click Selective startup , and then click to select the Load system services check box. If you can reproduce the issue after the computer restarts, the issue is related to one of the system services. Otherwise, the issue is related to one of the startup items. After you determine the items to which the issue is related, follow the steps in the "How to determine the service or startup item that is causing the issue" section to determine the individual service or startup item that is causing the issue.
To determine the cause of the issue, you can prevent individual services and startup items from loading when you restart the computer.
You can follow these steps. Click the Services tab, click Disable all , click to select the check box for the first service that is listed, and then restart the computer.

If you cannot reproduce the issue, you can eliminate system services as the cause. The option specifies that Windows automatically restarts your computer. Select one of the following type of information that you want Windows to record in a memory dump file if the computer stops unexpectedly:. To specify that you do not want Windows to record information in a memory dump file, run the following command or modify the registry value:.
The option records the smallest amount of information to help identify the problem. This option requires a paging file of at least 2 megabytes MB on the boot volume of your computer, and specifies that Windows will create a new file each time the system stops unexpectedly.
To specify that you want to use a small memory dump file, run the following command or modify the registry value:. To specify that you want to use a folder as your Small Dump Directory, run the following command or modify the registry value:. The option records only kernel memory. This option stores more information than a small memory dump file, but it takes less time to complete than a complete memory dump file. If you set this option, you must have a sufficiently large paging file on the boot volume.
The required size depends on the amount of RAM in your computer However, the maximum amount of space that must be available for a kernel memory dump on a bit system is 2 GB plus 16 MB. On a bit system, the maximum amount of space that must be available for a kernel memory dump is the size of the RAM plus MB. The following table provides guidelines for the size of the paging file:.
To specify that you want to use a kernel memory dump file, run the following command or modify the registry value:. To specify that you want to use a file as your memory dump file, run the following command or modify the registry value:. To specify that you do not want to overwrite any previous kernel or complete memory dump files, run the following command or modify the registry value:.
The option records the contents of system memory when the computer stops unexpectedly. If you select this option, you must have a paging file on the boot volume that is sufficient to hold all the physical RAM plus 1 MB.
The extra megabyte is required for a complete memory dump file because Windows writes a header in addition to dumping the memory contents. The header contains a crash dump signature and specifies the values of some kernel variables. The header information does not require a full megabyte of space, but Windows sizes your paging file in increments of megabytes.
