Simplicity is the answer when trying to prevent computer crashes. If you don’t want to have to deal with a fatal computer issue on your Windows system, then the solution can begin with doing a Windows Update. Ensure that your system is set to update automatically. Scheduling regular virus scans of your computer is another way to prevent future problems, as is ensuring that you have some kind of firewall installed on your computer. Without a firewall, unauthorized entry onto your computer can occur, which can lead to crash-causing malware and other files being installed and executed on your system.
