Thank you for responding! I posted my S/N but it got removed. It's: CND5117HRJ

Also, I did not install any new hardware, I was given this laptop for a windows reinstallation, I presume it has been tampered with because it has a 120g ssd in it. I managed to install drivers manually using hardware ids but I'm unsure about the hardware inside, and if everything is actually recognised by windows 7

I also tried downloading HP Support Assistant but that didn't really help me

• Are you getting any error message while installing the HP Support Assistant?
• What happens when the computer is started?

Keep me posted for further assistance.

No errors while installing, and windows boots fine thanks to the drivers I manually installed from ini files.
