It means that your computer has a serious issue that can't be resolved by any other solutions.

In that case, you need to uninstall any hardware you've recently installed.

You can also disconnect all hardware attached to your PC, then restart the computer. If the error continues to appear, you will need to install the device one at a time while restarting your computer every time to identify the hardware that causes the error.
