Starting an Acer Aspire laptop in safe mode is one of the best ways to begin the troubleshooting process if the computer is not functioning normally. Safe mode is a minimalist way to start your computer; in safe mode, only the files that are essential to Windows functionality will run at start up. This mode exists to diagnose and, if possible, remedy any software-related issues causing Windows to malfunction in its normal boot mode. Users can boot to safe mode on an Acer Aspire in three easy steps.
Power on your Acer Aspire laptop computer.
When you see the Acer splash screen--this contains the Acer logo and usually reads "Empowering People"--repeatedly press the F8 button. You can stop when you see a blinking underscore ( _ ) character. Wait a moment, and a list of boot options will appear.
Use the arrow keys to select "Safe Mode," then press "Enter. The Aspire will then boot to Safe Mode.
You have to be quick on pressing the F8 button; if you wait too long, or if you don't press it long enough, the Aspire will boot to normal Windows.
Most Acer Aspire computers will list multiple boot options when accessing the F8 boot menu, and three of them are different versions of safe mode: safe mode, safe mode with networking, and safe mode with command prompt. These modes are there to help resurrect a computer that does not boot properly in a normal Windows environment, and in most cases, standard safe mode can fix the issues at hand. Unless you absolutely need networking capabilities or know how to operate a DOS-style command prompt, do not select anything other than safe mode.
