(Redirected) Black screen no signal after Alienware Respawn update

I was initially trying to update Windows 8 to Windows 10. After having an installation error an Alienware Respawn message popped up about updating it before upgrading to Windows 10. I decided to go ahead and try it, after the update my computer restarted and sat a black no signal screen. After a couple hours I figured nothing was happening so I reset my computer. Now every time I boot up all I get is a black screen with no signal. I've tried switching out the hdmi cables and it didn't fix it.
