A user reports that their computer has started to shut down randomly. During your initial assessment, you learned that the user recently installed new software for photo editing that requires substantial system resources. What should be your immediate next step in troubleshooting this issue, according to best practices?
Inform the user to unplug the computer from the power source to prevent further unexpected shutdowns.
Perform a backup of the user’s system to prevent any potential data loss during problem resolution.
Safely power off the computer and add an additional hard drive to allow ample disk space for the new resource intensive software.
Reinstall the operating system immediately, as the new software could have caused system instability.
