Three long beep alarms are a memory issue.

Troubleshooting:

1. First clean up the memory module, remove the memory module (use your fingers to pull the card of the memory slot to both sides), wipe it with an rubber band, and then reinstall the memory module (align the memory module with the bayonet, hold both ends of the memory module, and press it down slightly). Turn on the computer to see if it can start the computer. Most of the computer beeping problems can be solved.

2. If the first step is still invalid, then you can only replace the memory slot first, see if the slot is broken, and then reinstall the memory.

3. If the problem of Changming cannot be solved, it means that the memory module has been damaged and needs to be replaced.

We turned on the computer and found that the display was black. The host also constantly discovers 3 short and 1 long sounds.

We press the power button of the main unit for 5-8 seconds and then release it, after which the computer will shut down.

We turned off the power switch, and then we came to deal with the keyboard, check whether the keyboard interface is loose, and deal with the loose ones.

Take out the memory module on the motherboard and erase the metal sheet with an eraser; If you have a discrete graphics card, you can also deal with it in this way, and if you can, use a hair dryer to remove the dust. After installing back in the memory, the problem of the graphics card being able to boot up is solved.
