1. Try closing other software. When you are ready to shut down, turn off all software in advance, such as QQ, browser, office software, etc.

2. Task Manager Press and hold ctrl+alt+delete, and Windows Task Manager will appear. Click "Shut Down" above to shut down.

3. Quick shutdown Press and hold the Windows+u key to shut down (remember to cut the input method into English).

4. Forced shutdown Find the power button of the computer and press it for a few seconds to force shutdown.

The computer always shuts down automatically for the following reasons:

1. There is too much dust. Too much dust on the computer leads to abnormal heat dissipation. Too high a temperature will burn out computer hardware, such as CPU and motherboard. The computer will automatically shut down to protect itself. Dust the computer regularly and reapply CPU silicone grease to ensure the normal heat dissipation of the computer.

2. Fan failure. Observe whether the CPU fan and graphics card fan work normally, and replace them in time if there is any abnormality.

3. Temperature monitoring. Master Lu has the function of "high temperature alarm" in temperature management to protect computer hardware in real time.

4. The virus starts. Sometimes some viruses will run programs indefinitely in the background, causing the computer to crash and paralyze. Some computers have protective measures and will automatically shut down to avoid danger. Using "360 security guards" to "completely kill" computers can completely eliminate the hidden dangers of viruses.

5. Insufficient memory. When the memory capacity is too small, it can generally run normally, but when running a large 3D game and needing a lot of memory, there will often be a sudden automatic restart. At this time, only upgrading the memory can meet the demand.

6. Hardware failure. Such as power failure, motherboard short circuit, etc. You can replace the hardware in a professional computer repair shop.
