The yellow triangle with a black exclamation mark in Device Manager indicates that the device is not properly recognized by Windows. This can be due to a number of reasons, including a missing or corrupted driver, a hardware conflict, or a problem with the device itself.
Since you've already tried updating the drivers, the next thing you can try is to uninstall the device and then reinstall it. To do this, follow these steps:
- Open Device Manager.
- Expand the "Other Devices" category.
- Right-click the device with the yellow exclamation mark.
- Select "Uninstall device."
- Click "Yes" to confirm.
- Restart your computer.
Windows will automatically reinstall the device driver the next time your computer starts up. If the device still doesn't work, you may need to contact the manufacturer of the device for further assistance.
Here are some other things you can try:
- Check the physical connection of the device to your computer.
- Make sure that the device is turned on.
- Try a different USB port.
- Update the BIOS on your computer.
