Editing Windows Diagnostics (section)

== Windows 7 freezing ==

=== Confirm that display drivers are up-to-date ===

''Right click'' on the desktop and open the display control panel software & check for updates. 

=== Verify hard drives ===

* '''Start Menu''' > '''Computer'''
* Select a hard drive > ''right click'' > '''Properties'''
* '''Tools''' tab > '''Error-checking''' > '''Check now...''' button
** The drive cannot be in use for the '''Automatically fix file system errors''' option to be selected.
** Uncheck that option to get a report. If no errors are found then no action is required. Otherwise, re-run and the system can attempt to fix the errors after a reboot.

=== Check for corrupt system files ===

Running a shell as Administrator:

<syntaxhighlight lang="powershell">
> sfc /scannow
</syntaxhighlight>

=== Check for bad RAM ===

* '''Start Menu''' > '''Run''' > ''Windows Memory Diagnostic''
* ''Restart now and check for problems''

=== Check for corrupted file system ===

<syntaxhighlight lang="powershell">
> chkdsk /r
</syntaxhighlight>

=== Check for hanging drivers ===

With WPA installed, open a shell as Administrator

<syntaxhighlight lang="powershell">
> xperf -start perf!GeneralProfiles.InBuffer && timeout -1 && xperf -stop perf!GeneralProfiles.InBuffer myTrace.etl
</syntaxhighlight>

* Hit <kbd>Enter</kbd> once to start the command. 
* Right after the system stops hanging, press <kbd>Enter</kbd> again. 
* After some time a log file MyTrace.etl will be produced. 

''Actually, that command won't work in Powershell. It creates a system trace that won't necessarily be all that easy to interpret.''
