How to Start Computer in Safe Mode and Reasons to Do So
Here is a guide to start your computer in safe mode. Safe Mode is the Windows diagnostics mode. When you start the
computer in Safe Mode, only the specific components that are needed to run the operating system are loaded. Safe
Mode does not allow some functions, such as a connection to the Internet, depending upon the Windows version. Safe
Mode also loads a standard video driver at a low resolution. Due to the low resolution, your programs and the Windows
desktop may look different from usual and the desktop icons may have moved to different locations on the desktop. It is
useful for flashing your drive (updating firmware) as well as other things such as:
Removing Viruses / Spyware
Often the only way to remove certain persistent virus and spyware programs is to run your system in Safe Mode. Many
forms of malicious software will protect or reinstall themselves constantly if they are allowed to start in the first place.
These programs will situate themselves in one of the many autorun locations in the Windows registry and file structure.
When Windows is started normally, so is the offending software, running as a process in the background.
When you start the PC in Safe Mode, these autorun locations are not used, and no software is started automatically.
This can allow virus and spyware removal programs the opportunity they need to remove the malicious software
completely.
If you are having virus or spyware problems on your PC, you should always run antivirus and anti-spyware programs in
Safe Mode to ensure that they have maximum effect. Download the latest version of the software (e.g. MalwareBytes)
before you go to safe mode so that you don’t need networking.
Running System Restore in Safe Mode to Recover a Non-booting System
If you have System Restore enabled on your system, you may still run into problems with software or bad drivers. If your
Windows XP installation will not boot normally, how do you get to your restore points? You can go to the most recent
restore point by using the “last known good configuration (your most recent settings that worked)” option in the
Windows advanced options menu, but if that does not fix your problem, use Safe Mode. Note that you cannot create
restore points in safe mode; only load them.
Troubleshooting Software Problems
Have you ever installed new software and found that your PC now refuses to even boot? With the range of possible
hardware and software configurations for PCs, it is practically impossible for software makers to test fully their
applications in all circumstances. Faulty drivers or software can cause a whole world of problems on a Windows system.
Constant crashing or failure to even boot are two of the most common symptoms. Fortunately, Windows Safe Mode
gives you a chance to put things right by disabling or removing the offending software.
Fixing driver problems
If you have installed a new driver for your graphics card or other peripheral, and your PC has gone haywire as a
consequence, Safe Mode can help you reverse the damage. The most common signs of driver malfunction are blue
screens and other crashes during the Windows loading process.
Of course, you can uninstall and roll back device drivers in Windows XP, but this comes as little consolation if you cannot
boot correctly into the operating system. By booting into Safe Mode, you can generally bypass the faulty drivers (since
Safe Mode uses its own set of default drivers and ignores non-essential peripherals like sound) and get to the operating
system where you can remove them.
