Does anyone know what is causing this issue?

Hey guys, been trying to reinstall macos high sierra on my 2009 27inch imac through a bootable USB drive. Followed all the steps to do so but I don’t think it installed properly. I have also tried using the CMD + R option to reinstall Is there something wrong with the hardware or is it a glitch in the macos version that I installed? I haven’t been able to boot it up but before it froze up, I was able to use it without any issue. Attached is the picture of the lines look at during the boot up.

The SSD that I am running is the intel ssdsc2mh250a2

Thanks in advance for all the help!
