PC turns off when USB is inserted
Here are solutions that can help you.
1] Update USB Driver
Uninstall Driver Universal Serial Bus (USB) and then reinstall and check.
- Press Win + R to open a Run window.
- Type “ devmgmt.msc ” and press Enter. This will open Device Manager.
- Search for USB Driver. Right-click on them one by one and click Uninstall to remove all of them.
- Keep the computer connected to the Internet, preferably via a LAN cable, and reboot the system.
- While restarting, the computer will attempt to reinstall all previously deleted drivers.
Check if it fixes the problem. If not, proceed to step 2.
2. Check the external devices connected to the USB slot
Some devices, such as several hard drives, with high power requirements. In case your computer is unable to handle it, it will likely crash. To isolate this possibility, try connecting external USB devices to other computers using less configuration. Check if it works with them. If not, then the external device is faulty.
Start the ” Troubleshooter ” Hardware and Device Troubleshooter and see if that helps.
4. Disable USB port
This is not the right solution. But if the work is more important than connecting the USB devices, then it can be considered. If the steps mentioned above fail, it probably means the problem is with the hardware. So you can disable USB until sending your system to a hardware technician. The procedure is as follows.
- Press Win + R and open the Run window. Type “ devmgmt.msc,” and press Enter to open Device Manager.
- Right-click on the USB Driver and click the option to “ Disable device ” to turn off the device.
Please reboot the system and use your system until it is sent for hardware-level repair.
5. Change the power supply unit
Those who are a bit familiar with the hardware can try this solution on their own.
- Change the power adapter if it is a laptop and check if it helps.
- Change the system power supply.
The power supply unit may be faulty if the computer has been upgraded or reused.
6. Check the USB connections
Those who can troubleshoot hardware (at least at a basic level) can try to check if the USB port is tightly connected to the motherboard using the connectors. Other than this, check if their metal contacts are touching each other. That could be the reason for the shutdown.
