TroubleshootingStartup Failures

A computer that will not start can be very

frustrating and impacts a users ability to get workdone.

Understanding what happens during startup canhelp you isolate the problem and select/use theright tool to get the computer back online.

The symptoms of a startup failure differ depending

on where in the process the failure occurs.

The first step to take when a Windows 8 computerfails to start is to determine exactly where in thestartup sequence the problem occurs.

POST Failures If a computer fails to make it through the

POST successfully, the problem isunquestionably hardware-related.

In most cases, the BIOS will display an errormessage or produce a series of beepsidentifying the exact problem causing thefailure.

Consult the BIOS documentation for moreinformation on its error messages and/orbeep codes.

Driver andService Failures

When a startup failure occurs before the logon userinterface appears, the problem could behardware-related, but it is most likely due to an issuewith one of the drivers or services that the kernel isattempting to load.

To locate the offending driver or service, firstattempt to get the computer started using the SafeMode.

Then you can examine the event logs, enable theboot log, and run the System Information tool to

gather information on what is affecting the startupsequence.

Finally, use Device Manager or the Services consoleto disable the offending drivers or services.



9/25

Logon Failures When the startup process fails after the user

has supplied logon credentials, the problemis most likely due to one of the applications

running from the Startup group. To troubleshoot this type of problem, boot

into Safe Mode.
