You refuse to tell anything about some "PC" like its hardware, what operating system it might have or had, what you want that SSD to do in the computer, what you see on the screen of the "pc" when a "fails to load" happens. And exactly what "load" might mean. Start up the computer's OS normally or put new OS files onto a blank drive?
Do you expect Windows already in the PC to start up normally? Or is there any OS at all?
I would expect a blank drive of any type, HDD or SSD, to be ia problem if it has not been activated and formatted correctly (if it needs to be) and partitioned in a Windows OS of most types that is already running in the computer. If no system files on any drive, you will have to boot from a system installation disk and get the SSD recognized as the destination for the new Windows OS files to be put on it correctly.
That is all that can be guess from your information, which was almost nothing.
