What should I do if my computer cannot be started after not being used for a long time?

If the computer cannot be started after not being used for a long time, it is necessary to check and troubleshoot the power supply, monitor, graphics card, memory stick, hard disk, motherboard and other components. Detailed introduction: 1. Check the power supply, check whether the power supply is normal, observe whether the power plug and socket are in good contact, and whether the power cord is damaged or aged. If the power supply is normal, you can try to replace the power cord or power plug to see if the problem can be solved; 2. Check the monitor and graphics card. If the power supply is normal, it may be due to a problem with the monitor or graphics card that cannot start. Check whether the monitor is connected properly, etc.

When the computer cannot be started after being unused for a long time, you can take the following measures to solve the problem:

1. Check the power supply

First, check whether the power supply is normal. Observe whether the power plug and socket are in good contact, and whether the power cord is damaged or aged. If the power supply is normal, you can try replacing the power cord or power plug to see if that solves the problem.

2. Check the monitor and graphics card

If the power supply is normal, it may be due to a problem with the monitor or graphics card that prevents the computer from starting. Check whether the monitor is connected properly and whether the plug is loose. If it is an independent graphics card, you need to check whether the graphics card is installed correctly and whether it is in good contact with the motherboard. If there are no problems with the monitor or graphics card, you can try replacing the monitor or graphics card to see if that solves the problem.

3. Check the memory module

The memory module is one of the very important components in the computer. If there is a problem with the memory module, the computer may not start. First, unplug the memory stick, wipe the golden finger part with an eraser to remove the oxide layer, and then re-insert the memory stick. If the memory module does not fail, it may be due to a problem with the slot. You need to clean the dust and debris in the slot and then reinstall the memory module.

4. Check the hard disk

If there is no problem with the memory module, it may be due to a problem with the hard disk that the computer cannot start. Check whether the hard drive is installed correctly and has good contact with the motherboard. If it is a mechanical hard drive, you need to check whether the hard drive has bad sectors or damage. If it is a solid-state drive, you need to check whether the main control chip of the solid-state drive is faulty. If there is no problem with the hard disk, you can try replacing the hard disk or main control chip to see if the problem can be solved.

5. Check the motherboard and other components

If the above four steps do not solve the problem, it may be due to a problem with the motherboard or other components that prevents startup. First, check the motherboard for obvious burns, cracks or blown capacitors. If these phenomena occur, the corresponding parts need to be replaced. If these symptoms do not occur, you can try clearing the CMOS information and resetting the BIOS. If the above steps do not solve the problem, it may be due to problems with other components that prevent the startup. You need to check whether other components are faulty one by one.

In short, when the computer cannot be started after being unused for a long time, it is necessary to check and troubleshoot the power supply, monitor, graphics card, memory stick, hard disk, motherboard and other components. During the troubleshooting process, it is necessary to eliminate possible faults one by one and pay attention to safe operation. If none of the above steps solve the problem, it is recommended to seek help from professional maintenance personnel.
