Safe Mode is a specially designed mode of the Windows operating system that starts your computer using only those programs required to successfully load your operating system. Any other program is disabled, which makes Safe Mode ideal for troubleshooting computer issues like hardware failures or viruses. You can start your eMachine computer in Safe Mode using the Windows Advanced Boot Menu.
Turn on your eMachines computer.
Press the "F8" key as your computer starts up. A screen called the "Windows Advanced Boot Options" menu will appear on your monitor.
Highlight "Safe Mode." Tap "Enter" to start your computer in Safe Mode.
