Windows 10: how do i fix my pc?!

I bought a used desktop and when i started it up it was working fine until it started acting slow and wouldn’t even shut down sometimes or restart. The computer also kept getting stuck on the loading screen when i started it, i had to keep disconnecting it from the outlet and plug it back in. I’m also supposed to have 2Tb of storage but for some reason it had the previous owners data and when i tried deleting it it kept restarting or wasn’t registering or would just say i don’t have access. I ended up just doing a reset but then it wouldn’t let me log in with my pin and it said i had to set it

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??
