Its struggling to find the Hard drive or SSD.
Is the hard drive recognised in the BIOS?
power on then power off after 5 seconds - repeat three times and then let it try and boot if the hard drive is seen at all it should boot to advanced tools where you can try a startup repair.
otherwise download and make a win10 iso to burn to disk or USb set bios to boot from USB or DVD and boot from the iso to attempt repairs
however it is possible the hard drive is failing.
