Windows 10: HP Startup Black Screen - Strange behaviour!

    HP Startup Black Screen - Strange behaviour!

    This morning my laptop stopped working. When loading what appears is just a black screen. Nothing more.
    The last thing I did on my pc was watching a film and I didn't download or install anything.
    I tried to make sure that the screen isn't broken by plugging it to a monitor, but it still showed no response.
    Afterwards I tried to enter the BIOS. By pressing ESC during loading it gives me a startup menu with multiple choices:

    • System information
    • System Diagnostics
    • Boot Device Options
    • BIOS Setup
    • System Recovery

    First of all, since something is appearing, this means that the screen is working (and i guess also the graphics card should be working properly).
    So I think it is because something happened with the OS (could be an update, not sure, I had Windows 10).
    Coming back to the menu, this is what happens:

    • System information: just gives me some info on the pc
    • System Diagnostics: lets me check the memory (should work but takes 20min and not sure if I would understand the output) and hard disk (which doesn't work, because it says that the software for checking isn't installed)
    • Boot Device Options: enables me to select different Boot options
    • BIOS Setup: tried changing some options but didn't help
    • System Recovery: when launched the screen becomes black again, and after 5min a screen with HP logo (and under the text "System Repair") appears, but goes away after 30s and the screen stays black again (end result: nothing seems to have happened).

    I also tried to install Windows 10 again, by booting an USB I have, and when running the HP logo appears with a circle that is loading and after some seconds of loading everything remains black again.
    Overall I think it is something that can be repaired (I think somehow by installing a new OS) since we can still access the BIOS and other options (that doesn't really work), but I'm not sure how, I tried almost everything.
    Does someone has some ideas?

    You have to figure out how to boot from alternate media so you can try some repairs. It may very well be something hardware related. You might want to run those diagnostics, then upload the results here so we can help you to interpret and act upon them. OTOH, other forum regulars may have other and better suggestions. People?

    Thanks for the reply, I have tried to run the memory test, but it just says PASSED and nothing else (no log file or other).
    I'm not sure what else I can try. Can someone help?

    Are you able to select an alternate boot source in the BIOS? Will it let you attempt to boot from another bootable drive? I assume you must have another computer (or access to one) because you're posting here. You might want to try building a Macrium Rescue Media disk (here's a link to a Macrium KB article on that subject: "Creating Rescue Media"). OTOH, you could try using Kyhi's Rescue Disk (a TenForums item: Windows 10 Recovery Tools -- Bootable Rescue Disk) instead. If you can get either of those items to boot your PC, you can use them to attempt boot repairs (which may very well fix your problems). If that doesn't work, there are other things to try, so please keep us posted on your progress (or lack thereof).

    If there is any problem posting then use one drive or drop box or google share links

    3) Insert the windows 10 iso into any USB port
    4) Power on the computer and repetitively click the F9 key
    5) Select external USB hard drive

    9) Click system restore
    Start with the oldest restore point and keep repeating until you complete the newest restore point.

    35) bootrec /fixmbr
    36) bootrec /fixboot
    37) bootrec /scanos
