Trying to reinstall windows.

My laptop just this morning did not wanted to boot into windows any more.Blue screen and say windows can't start. So i took out the laptop ssd and full format it in a other pc. Still if i try to install any os it installs untill file installation complete when it reboots it just shows lenovo logo then try to complete installation it just show black screen nothing else. It can't seem to boot into a windows. I can't flash the bios because all bios files for this unit is in .exe format and not in usb files. I tried 3 other hard drives, difrend types off ram. I put in a new bios battery and put new pasted on cpu and gpu. I am realy desprate to fix this laptop. I did not replace the hard drive connector yet?. Bios is version 2 of....37 and does not show serial number or lenovo is say's unkown device.
