- Try to replace the power cord and power adapter: Sometimes the power cord or power adapter may be damaged, causing the computer to fail to boot normally. You can try using other reliable power cords and power adapters to troubleshoot the problem.

2. Hardware problems:

- Check hardware connections: Check the hardware connections inside the computer, such as memory modules, graphics cards, hard drives, etc. Make sure they are firmly attached and not loose or detached.

- Remove and reinstall hardware: If possible, you can try to remove and reinstall hardware to make sure they are connected correctly.

- Check for hardware faults: Some hardware faults may cause the computer to fail to boot normally. For example, damaged memory module, graphics card failure, etc. In this case, the failed hardware may need to be replaced or repaired.

3. Battery issues:

- If you are using a laptop, check if the battery is drained. Try connecting the power adapter and charging it, then try turning it on again.

4. BIOS setting issues:

- Check BIOS settings: BIOS is the computer’s basic input and output system, controlling the computer’s hardware and startup process. If the BIOS settings are incorrect, the computer may not start properly. You can try to enter the BIOS setting interface to restore the default settings or adjust the corresponding settings.

5. Software problems:

6. Other issues:

- Virus infection: Some malware may cause the computer to fail to start normally. You can try running a full scan with anti-virus software to remove any viruses or malware.

- Software updates: Sometimes software updates may cause computer startup problems. Try rolling back or uninstalling recently installed software updates to restore your computer to startup normally.

It should be noted that the above are some common solutions, but the specific situation may vary depending on the computer model, operating system and hardware configuration. If the problem persists, it is recommended to consult the computer manufacturer's technical support or seek professional help.

In summary, the computer's unresponsiveness may be caused by power problems, hardware problems, battery problems, BIOS setting problems, software problems, virus infections, etc. Solutions include checking power connections, hardware connections, battery levels, BIOS settings, troubleshooting hardware failures, checking software issues, anti-virus scans, etc. When dealing with the problem of a computer that is unresponsive on startup, you must be careful to ensure data security and back up important data when necessary.
