I have done two clean installs does that mean you have the DVD for your previous op sys? (Windows 7 or 8.1?)
You could buy a new harddrive and install your previous op sys on that.
It could just be that you haven't got the Windows 10 drivers for the hardware, or when you did a clean install of previous op sys you didn't download the drivers for that either.
A few more details would help, what was your previous op sys and what dvds do you have? and what is the make and model of your laptop and did you get the drivers needed?
