Hey Penz, do you know what your mother board is? Or maybe just the model and type of computer if you know that. If not can you go here (
https://www.belarc.com/products_belarc_advisor) and download Belarc and run it and post either a screen shot of the information or copy and paste the data. That might give me a little more information to work off of. I haven't ran that in a while but it might also display keys for some software. I don't remember if it does or not.
You may want to blank that out if it does. Is your computer a tower? Have you ever done anything like taking out motherboards or anything like that?
