Using Windows “Safe Boot” To Diagnose and Repair Problems

When something goes wrong with Windows it can be very difficult to diagnose or repair, and there are times when booting your computer into Safe Mode just isn’t good enough.  Safe Mode, a special diagnostic mode built into Windows strips the OS of all drivers and start-up software and presents you with a very limited version of Windows in which to diagnose what might be causing a problem, and repair it.  Many Windows features simply won’t operate in Safe Mode so there’s not very much you can do.

Fortunately though there is an alternative and it’s in every version of the operating system (XP, Vista and Windows 7).  This is called “Safe Boot” and you can find it in the MSConfig panel.  To open this type msconfig into the Start Menu search box in Vista or Windows 7, or run msconfig from the run option in XP.

Under the Boot tab in the MSConfig window you’ll see the Safe Boot option as a tick box.  Turning this on will make Windows use the Safe Boot option every time thereafter.  When you want to stop using Safe Boot and return to starting Windows normally you’ll need to return to the MSConfig panel and untick this option.  There are also several other options here including Minimal Boot, which will take you into the full Safe Mode, but the standard option will normally be enough for most people.

The Safe Boot screen, as you can see here is a half-way house between the full Windows desktop and Safe Mode.  What you will find though is that most of your hardware drivers will be installed and working though your startup software will still be disabled.

So when might you want to use Safe Boot?  Occasionally you will encounter a problem in Windows that you will need to go into Safe Mode to repair.  As I mentioned earlier however Safe Mode won’t allow you to perform some Windows tasks, and this is where the Safe Boot mode is useful.  You may also suspect that your problems aren’t being caused by a hardware driver, but by software instead.  This diagnostic mode enables you to have a full Windows desktop where nothing loads at startup and where you can run and check programs individually to see what effect they are having on your system.

As I have already mentioned Safe Mode is extremely limiting, not just in the very low screen resolution that it gives you.  If you need to run full diagnostics on your copy of Windows, to see what’s going on under the hood, or if you need to test individual software packages in a safe environment where they will be able to run properly then Windows Safe Boot is the way to do it.

Remember though that you will need to turn off Safe Boot when you are done, or else Windows will start permanently in this mode.  I have found this to be a very useful diagnostic tool in Windows and it’s extremely underused because, frankly, many people simply do not know that it exists.  Hopefully you will find it useful too.

Monitor and Troubleshoot Your PC’s Operations in Real Time

One of the most common questions I’m asked when people email me with PC questions is how they can find out exactly what it is that’s causing X disk operation or eating up Y memory or Z processor cycles.  The good news is that this is actually really easy to find out.

In Windows Vista and Windows 7 the new Resource Monitor is able to give you real-time information about just about everything going on inside your copy of Windows.  You can access it by typing the word resource into the Start Menu search box.

The Resource Monitor itself is split into different tabs and panels.  The tabs along the top will give you an Overview of your PC’s and Windows operations, but there are also tabs to give you detailed and in-depth information on your CPU, Memory, Disk and Network.

Each tab is split into collapsible panels that give you detailed information.  Where it comes in especially useful is in the following scenarios.

Scenario A – Your PC suddenly slows down at random moments and you can’t check why.  You have a look in the Task Manager but can’t see what it is that is chewing your processor cycles or memory.  Leaving the Resource Monitor open will give you much more detailed information than you will find the Task manager, including real-time graphs of exactly what’s going on.

Scenario B – Your network connection is slow and you don’t know why?  Using the Resource Manager you can see exactly what is using your network connection and how much bandwidth it’s using, not just overall, but split across your different connections and separating out Internet and local network traffic.

Overall I can’t recommend the Resource Monitor highly enough for helping diagnose and repair problems with slowdowns and bottlenecks on Windows PCs.  The Resource Monitor is very easy to use and understand and give you details of exactly what program or process is eating away at your valuable computer resources.

Backing up and Restoring Windows Drivers

The hardware driver support in Windows 7 is just fantastic, especially with consumer hardware with more and more companies submitting their drivers for official certification from Microsoft than ever before.  This not only means driver support on the Windows 7 installation DVD, but also through Windows Update.  You can still find computers however for which the driver support is lacking, my own laptop, the Dell M6600 is a great example of this where the drivers for the graphics (both internal Intel and nVidia), USB3, biometrics, touch-panel, Wi-Fi, Ethernet and SD Card reader are not installed automatically by Windows, nor by Windows Update.  Each one requires a driver download from the Dell website (which is annoying!)

So how do you back up the drivers in your Windows installation and how can you use these?  In all versions of Windows the drivers are stored in the C:\Windows\System32 folder in the sub-folders Drivers, DriverStore and if your installation has one, DRVSTORE.  These folders contain all the hardware drivers for your operating system.  In the folder location, C represents the drive on which you have Windows installed, this may be a different letter on your system.

You can simply copy these folders out to seperate storage (DO NOT MOVE THEM) such as an external USB drive or Pen Drive.  When time comes to reinstall the drivers you can copy the folders back.

Now there are a couple of ways to reinstall the drivers.  The easiest way is to simply restart the PC when the driver folders have been copied back to see if Windows automatically detects drivers for uninstalled hardware.  This is possible, but won’t be the case for all your hardware.

To install drivers for the missing hardware you need to open the Device Manager.  You can do this by typing Device Manager into the search box in the Start Menu.  You will see all your uninstalled drivers highlighted with a small yellow warning triangle icon.  You need to Right-Click on each one and select Update Driver.  Because the correct drivers are already in the drivers folders on your computer, telling Windows to find the drivers automatically should always install the correct one.  You may however, in some cases, have to tell the Device Manager which folder to look for.  You can either point it directly to one of the two drivers folders, or just at the System32 folder; making sure you tick the box “include subfolders”.

There is an important caveat with this.  The drivers for 64 bit (x64) and 32 bit (x86) versions of Windows are usually different.  This means that if you copy x86 drivers into an x64 copy of Windows; or vice-versa, they will not install.  Windows will recognise them as being incorrect.  You cannot use this method therefore when migrating your system from the 32-bit version of Windows to the 64-bit version when, for example, adding more memory to your PC.

You CAN use this method to migrate drivers between Windows Vista and Windows 7 (and back again) as both operating system share the same driver model, but again not between x86 and x64 builds.  You CAN’T use this to migrate Windows XP drivers to Vista or Windows 7 however as Windows XP uses an older driver model and the hardware drivers for XP are not compatible with the newer versions of Windows.
