Internet Explorer Troubleshooting
Windows isn't behaving properly (miscellaneous)
The notes on this page are not intended to address any specific problem,
but the rather undefined problem of a Windows machine being either unstable
(i.e. crashes or locks up) or being unwell - things just don't work like
not shutting down for example.
This is a general checklist of things to check or things to do:
- Check the amount of free space on the C drive. It should be (as
a guide) at least 10% of the total size of the disk.
- Check you have up to date anti-virus. If you don't have an up to
date anti-virus product then take a look at
which lists a number of anti-virus products which are free for home/personal
- Do a complete anti-virus scan of your pc.
- Try a spyware removal program, these also remove Trojans and other
nuisance programs. I would recommend either spybot from
or ad-aware from www.lavasoft.de,
both of which are free for personal (non-commercial) use. Let it run
and do a complete scan. Trojans/worms etc can cause a variety of problems
- Open a command window and type:
chkdsk c: /r
This command initiates a check (and repair) of the disk, including
a check for bad sectors. If you are using Windows NT, 2000 or XP then
this will offer to run the next time you reboot your computer - accept
this option, reboot and let it run. After it has finished and Windows
starts, you will need to look in the application event log to see the
output from chkdsk.
- Empty out any temporary directories. For example open a command
window and type:
then using windows explorer find that folder and delete everything
in it. You may find that there are a few files in it that you cannot
delete because an application (or Windows itself) has these files open.
This doesn't matter, but do delete all the files that Windows will let
- Delete any temporary internet files - do this by running up Internet
Explorer, Tools > Internet Options and click on "Delete Files..."
- Re-apply the latest service pack for your version of windows. Windows
update is not sufficient. Download the latest service pack and run it.
Do this even if you are already running with the latest service pack.
This should resolve a number of issues with corrupt or inconsistent
- If you are having problems related to your browser (either internet
explorer or windows explorer) then download and run the latest service
pack for internet explorer. (You can also try repairing internet explorer
- this option is available to you if you try to uninstall internet explorer.)
- If you are running Windows 7, Vista, XP, W2K or NT then it is worth having a quick
look in the Application and System Event logs. For XP and W2K these
are accessible under "Administrative Tools" in the control panel. Most
systems contain some errors, and not all errors recorded here are anything
to worry about.
- Run Device Manager. (For Windows XP and W2K this is accessible under
"Control Panel" > "Administrative Tools" > "Computer Management". It
is also available by right clicking "my computer" in the explorer view,
selecting "properties" and then going to the "hardware" tab.) Do any
of the components listed have an exclamation mark next to them? This
indicates that a device isn't working correctly. The tree view should
be automatically expanded if there are any devices not working, so its
north worth hunting through the tree manually looking at each device

for Windows NT, 2000 and XP".

These notes have been tested with Windows XP, Windows
2000 and Windows ME.
