I try to install DirectX for a software, and then the system needs me to restart computer, the screen always stay black status after win logo when i try to restart computer.

I had find some article to fix this problem, for example, 3 times halt and start power to access Safe Mode, but the screen of computer still kept black status when i try to do it.

Where did you installed the ActiveX?
Was it from the trusted source?
Do you have access to the Window installation media?
Are you able to access the Windows Recovery Environment? (A blue screen with options).
