Stuck on "No Signal" screen while trying to upgrade to TP...

[FFugue]

I just started updating to Windows 10. On the Insider page I click on the button to start, it asked me to reboot, I clicked on ok. But now my computer won't turn on again. I'm stuck on a black screen (actually it's not a black screen, it says "no signal" on my monitor). I waited over 15 minutes and nothing's happening... Any ideas what could have happened? And how to fix it?

Ok, so I tried to reboot (holding the start button for 5 seconds), still got on the no signal screen, tried it again and it booted properly... Still on Windows 8.1, but now Windows Update is showing me an update available for Win 10 TP, so everything's good I guess. I'm not sure I understand what happened there, but as long as it's working again I'm happy!

no signal will indicate no display driver although im not sure how this info will help you.
