Prebuilt computer won’t install windows after replacing CPU and internal M.2 SSD

Need some assistance. I started out with a prebuilt gaming PC. The MB is a ASUS Prime B360M-A. I took the CPU (Intel I5 9600K) and the internal SSD (M.2 (500GB) and put it in my new computer that I built. It works great. The prebuilt computer I’m giving to my stepson. I replaced and installed the CPU with an Intel I5 9600K and a 1TB internal SSD. Am I wrong in assuming that Windows needs to be freshly installed back on the prebuilt computer that I reinstalled hardware? What’s steps do I need to do? I tried doing a Windows media download to a USB flash drive, but the boot up always freezes…. Either at the ASUS page or at the windows setup page and I lose control of my mouse. Any and all help is greatly appreciated. Thanks!

 

Buying a prebuilt pc

I am considering about getting a prebuilt gaming pc but I am worried it might not come with an activated key and I do not want to spend 150$ for a new activation key should I buy a prebuilt pc? or do I buy one from a popular brand? or do I just not buy a prebuilt gaming pc?

 

Installing New SSD Questions

Hello, I am installing a new SSD in my younger brothers PC and just want to make sure that I know what I am doing before I do it. Against my better judgement he bought a prebuilt PC from bestbuy that didnt come with an SSD so naturally his OS is on a HDD,
my question is what are the steps I should take to move his windows OS to the new SSD, start fresh with just windows, but keep it so it is the full paid version of window and he dosent need another key. Please help me understand so I do not brick his pc, thank
you.
