    So you only attempted to install updated drivers for your VPU?

    Look at this Microsoft page on GoBack issues if you have GoBack installed.

    A driver is nothing more than a software translator between your OS and hardware device.

    You are saying that you physically installed another VPU, you got an error message, you tried installing the original VPU and it still won't boot. Check your BIOS settings and make sure it's set to the original VPU and then try to boot into Safe Mode again. If you make it into Safe Mode uninstall the drivers for the VPU that was giving you trouble in the Device Manager.

    Post back with your results.
