Windows 10: Activation on one pc but not the other

So I have a pc with a i3-4160 that when I use my ssd on it windows is activated since I upgraded from win 8 but i decided to switch to a slightly older pc with a i5 in it but when I use my ssd on the i5, windows isn't activated. I dont need it fixed exactly but its a inconvenience to have to move my ssd over to the i3 for basic stuff such as changing my background, and if I can id like to do something about it.

:)

 

My PC suddenly says its not activated

I wish I could hands-on your PC .... it's a bit difficult explaining stuff...

 

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??
