I have a windows 10, 64 bit computer that belongs to my father. Two days ago when he woke up he had a black screen on his computer, and no internet signal (as evidenced by a laptop connected to the main computer's wifi). I believe he restarted his computer and the wifi issue resolved itself.

The message that briefly flashes on the screen states no vga signal, no dvi signal. I have replaced the cables with known working cables, including a dvi cable that it was not originally connected with. His monitor works at my house. My monitor will not work at his house. 

The lights on the computer itself do come on and I can hear the fan spinning. I attempted to reset the bios using these instructions from HP's troubleshooting :

1. Turn on the computer and repeatedly press the F10 key for eight seconds. 

2. Press the Down arrow three times.

3. Press the Enter key two times.

4. The computer restarts.

 

I tried several times, varying my timing slightly. It would not restart. I am actually not sure his computer is an HP. I will check tomorrow. Thanks for your help.

I'd start by trying a different display adapter.
