Windows 10: Black screen of death without signs of the keyboard working and with fan on

My laptop is an hp elitebook G4 it automaticcally installed the latest version of windows one day ago and now it gives me a black screen upon using the power button.I tried all the solutions on ibternet with the keyboard shortcuts to get it to bios restore and delete the previous update but it doesn't work in my case. I opened the laptop to try taking the battery out for 30 seconds and then replugging it, it doesn't look like it changed anything but I can see that when powering up the fan starts spinning.When powering up the power button stays on too but everything else in the keyboard doesn't

Almost Black Screen of Death?


Okay, so my sister was trying to watch a Blu Ray DVD in my computer last night, but of course it didn't work. She ended up watching a normal DVD and it was fine. After she finished, I turned off my computer normally. This morning, however, I tried turning on my computer and it gave me the normal code screen thing with quite text and a black background. This time, instead of booting normally it said "Press [Esc] to boot... (instert countdown here)" I waited and didn't press anything and it just came to a screen that was almost black and almost blue. The cursor didn't pop up and when I pressed Crl, Alt, and Delete it went back to the white text code screen. I attempted pressing Esc like it said, but it all led back to the almost black screen of death.
I called my one of my family members for help because they are a tech guru, and they suggested unplugging everything (which I had done and proved unsuccessful), taking out the RAM and putting it back it, and still nothing. They then suggested pressing F8 when I boot up my computer, and it comes to the pop up window with two things to select. One that's called Sata and the other that's called CD or something. I tried selecting both of them, but yet again, the almost black screen of death.
After my several attempts, my family member told me to try to safe reboot using the CD we have saved for my computer as a backup. There was no DVD in my computer during all these attempts.
Was this caused by the Blu Ray, and any ideas on what to do? Thanks!
