Does it boot into the bios or nothing works? Does your motherboard have integrated graphics you can try?
If you can get into bios, we can try to boot from Installer
Download win 10 installer from
Here and use the tool to make a win 10 installer on USB or DVD - your choice. You will need to use another PC to make it, obviously. Its a boot disc if nothing else
might help to dl your driver replacement, i think you can install them in safe mode
change boot order in bios so USB is first, HDD second
boot from installer
on second page of installer, after language choices, choose repair this PC, not install.
choose troubleshoot
choose advanced
choose start up repair - this might fix whatever went wrong as PC should have drivers for the GPU, it shouldn't have just stopped. This will ask for your logon info
If that doesn't fix it
boot from installer, choose repair PC
You know how to get to safe mode from here so see if you can reinstall driver in safe mode or have a look in device manager and see if there is a display adapter showing there. Check any yellow warning triangles
