    • Test the RAM modules for any errors using diagnostic software.
  • Check for Software Issues:
    • Run a virus scan to check for malware that may be causing the computer to shut off randomly.

Enhance System Performance and Security

1. Check for overheating issues by cleaning out dust from the computer’s fans and vents. Overheating can cause the system to shut down unexpectedly.

2. Update the operating system and drivers to the latest versions. Outdated software can lead to compatibility issues that may result in shutdowns.

3. Scan for malware and viruses with an updated antivirus program. Malicious software can cause system instability and shutdowns.

4. Run a system file checker scan to repair corrupted files that may be causing the shutdowns.

5. Check the power settings and ensure the computer is not set to shut down automatically. Adjust the settings if necessary.

Troubleshoot Power Management Settings

Next, update the BIOS to the latest version from Dell’s website. An outdated BIOS can cause power management issues. If the problem persists, check for any updates for Windows 8.1 that may address power management bugs.

Additionally, run a full scan with your antivirus software to rule out any malware causing the random shutdowns. If you use a docking station, try disconnecting it to see if the issue is related to that.
