When the computer fails to start after not being turned on for a few days, it may be due to a variety of reasons. Here are some common troubleshooting steps that we hope will help you solve your problem:

1. Check the power connection: First make sure the computer's power cord is properly connected to the power outlet and make sure the power outlet is working properly. If you use extension cords or power distributors for electrical outlets, make sure they work properly as well. Try changing the power cord or outlet to see if that solves the problem.

2. Check the computer hardware connections: Check whether the computer internal hardware connections are loose or detached. Open the computer case and check whether the motherboard, memory module, graphics card, hard drive and other hardware are inserted correctly, and make sure they are firmly connected. If you find loose or dislodged hardware, reseat it and make sure the connection is secure.

3. Clean the inside of the computer: If the computer has not been used for a long time, dust or dirt may accumulate, causing the computer to fail to start normally. Use a can of compressed air or a soft brush to clean the inside of your computer, especially the radiator and fan. Make sure there is good ventilation inside the computer and avoid overheating issues.

4. Restart the computer: Sometimes the failure of the computer to start is just a temporary fault. Try to press and hold the power button of the computer host for 5 seconds, then release it. After waiting for a period of time, press the power button again to start the computer. . This will allow the computer to restart and may resolve some temporary issues.

5. Check the monitor connection: If there is no monitor signal after the computer starts, there may be a monitor connection problem. Check that the monitor cable is plugged in and make sure the connection is secure. Try changing the monitor cable or connector to see if that resolves the issue.

6. Check the computer startup sequence: Sometimes the computer startup sequence is set incorrectly, causing it to fail to start normally. Enter the BIOS setting interface (usually press the Del, F2 or F10 key to enter), check whether the boot sequence setting is correct, and set the hard disk as the first boot option.

7. Check the computer battery: If you are using a laptop, check whether the battery is undercharged or damaged. Try connecting the computer to the power adapter, and then try starting the computer again.

8. Contact after-sales service: If the above methods do not solve the problem, it is recommended to contact the computer’s after-sales service center or professional maintenance personnel for further investigation and repair. They have more professional knowledge and equipment to solve computer problems.

It should be noted that when trying to solve computer problems, we should pay attention to safety and avoid touching internal parts of the computer or performing unfamiliar repair operations to avoid causing more serious damage or personal safety issues.
