  • Often, the USB cable itself goes out of order, so this should not be ignored either, because there is a mini-closure, which leads the system to an error 43.
  • If you try to connect some device that has an external power supply, but at the same time, the device itself is not plugged into the power outlet, then this action can also cause an error 43, since the PC has a high power consumption via the USB port , Which very often, is the result of an error.
  • Do not ignore and penetrate into your OS of malicious software, as the viruses are now so sophisticated that they can attack everything and everything, and therefore the errors in the system through their fault can be completely different. In this case, the best way is to scan your computer system with one of the antivirus programs.
