Using Windows repair to fx a slow Windows 7 machine; Lenovo Thnkstation C20, booted into Safe Mode as per instructions. The PC made all of the signs of rebootng but the screen has stayed blank ever since.
This means I don't know if the reboot has worked, where to click to go to the next phase, or how to get out of Safe Mode. There s NOTHING on screen.
What do I do to recover from this?
