According to the situation you described, the problem may involve multiple hardware or software failures. Here are some possible solutions:

Check whether the computer camera is damaged: the USB flash drive suddenly gets stuck when playing video, indicating that the probability of equipment failure is not high. However, this may cause problems with other devices connected to the computer, such as cameras and speakers. Check the camera of the computer for any physical damage, such as cable damage or the camera itself.

No noise after turning off the power supply: excluding damage, cables and other factors, some external devices connected to the computer may interfere with the normal work of other devices. It is recommended to try to connect different external devices (such as mouse, keyboard, headphones, etc.). ), restart the computer to determine which one is affecting the computer camera and speakers.

Update software: You can also try to update all relevant software on the computer, including drivers and operating system patches, to ensure that all components can work normally. If you have finished this operation, but still can't find a solution, please consider restoring or cleaning the computer system so as to restore the initial state of the computer.

If the above solutions can't solve the problem, you may need to seek professional technical support, or consider replacing hardware devices such as computer cameras.
