Windows 10: Splash screen hang

When a computer boots up , the first thing seen would be the splash screen and after which it goes to windows.

Mine , however , hangs at the splash screen.

What i have so far:

A bootable flashdrive with windows 10 installation,

1 x 250GB samsung ssd and 1 x toshiba standard hard disk of 3TB.

My test and results so far:

1) boot up with jut the 3TB drive.. boot jumps into bios immediately as it cannot detect the 3TBG drive
It is probably damaged (and it has no windows installed on it ) , called the vendor and they are willing to replace it as it is under warranty.

2) tested with just the 250GB Samsung SSD. Bios can detect.(Great news) , however , thats it. It will not go past the splash screen.

3) SSD with bootable drive to re-install windows on SSD. Bios can detect both. So now I click boot options and select the flash drive to re-install windows.

but I get this screen https://i.imgur.com/o6IV8XL.jpg. From the screenshot and I what I noticed myself , there seems to be a horizontal blue line there. Not sure what it is . Anyways I restart the computer , select boot options and select the SSD instead , however , I am getting that same screenshot too.

Can someone help please as I am out of ideas.
