Why does my PC turn on and off repeatedly after I turned it off?
This issue can be caused by several underlying factors. Here are some common causes and solutions:
- Power Supply Unit (PSU) Issues: A failing PSU can cause intermittent power issues, leading to repeated shutdowns. Consider replacing the PSU.
- Overheating: If your PC overheats, it will automatically shut down to prevent damage. Check for blocked vents or clogged cooling fans, and ensure proper airflow.
- Faulty Motherboard: A malfunctioning motherboard can trigger random shutdowns. Inspect the motherboard for any visible damage or loose components.
- BIOS Settings: Incorrect BIOS settings, such as improper power management or overclocking, can cause unexpected shutdowns. Reset the BIOS to its default values.
- Malware Infection: Malware can manipulate system settings and cause instability, leading to repeated shutdowns. Perform a thorough malware scan using a reputable antivirus program.
