To resolve power issues and connection problems causing your Windows PC to randomly restart without warning, start by checking the power supply unit (PSU) and ensuring it is functioning properly. Inspect the power cord for any damage and consider using a surge protector to prevent power surges.

Next, check the motherboard for any signs of damage or capacitor plague, which could be causing the random restarts. Run a root cause analysis to identify any underlying issues, such as malware or hardware problems.

Make sure to update your antivirus software and perform a full system scan to check for any computer virus or ransomware that may be causing the problem. Additionally, ensure that your Windows Update is up to date to fix any software bugs or security vulnerabilities.

Finally, monitor the computer’s temperature to ensure it is not overheating, as this could also cause random restarts. Consider using an uninterruptible power supply (UPS) to prevent power failures from causing unexpected shutdowns.

Managing System Features: Turning Off Automatic Restart and Disabling Fast Startup

To prevent your Windows PC from randomly restarting without warning, you can manage system features such as turning off automatic restart and disabling fast startup. To turn off automatic restart, right-click on the Start button and select System. Then, click on Advanced system settings, go to the Advanced tab, and click on Settings under Startup and Recovery. Finally, uncheck the box next to Automatically restart and click OK.
