So basically im bouta build a new computer, new case, new gpu, new cpu, new almost everything except the storage, that is a HDD that I store games on and a SSD which my windows os is installed on right now. (I'm using a desktop that I've played with for years at the moment I type this) I was wondering that if I was gonna boot my new pc on the SSD, is everything gonna just open fine and normal like it was my old pc or I gotta format it all and re-install windows from a usb key?

If the new motherboard has a different chipset than your current motherboard, then it would be wise to re-install windows.

What is your current motherboard make/model and what is the new motherboard make/model?

The best practice is a full wipe-and-reinstall. Sometimes it'll work, sometimes it will at first until you chase random bugs for a year, sometimes it will be broken from the start. But anything worth doing is worth doing correctly; you're slapping all your old drives and stuff from a decade-old motherboard into a new build that has technology that barely even existed back then. Just do it right the first time. Windows 10 tries to make it work, but the fact is that Windows is not designed to be modular in this manner unless you have a very specific type of Windows-to-Go installation (you'd know if you did).

You should take the opportunity to have a backup regimen if you don't already! If you're doing it right, the sudden loss of a storage drive should never cause important data to be lost.

Trying to use the old drive+OS in a new system, there are 3 possible outcomes:
  1. It works just fine
  2. It fails completely
  3. It "boots up", but you're chasing issues for weeks/months
#1 is the least likely to happen.

Save off personal files/data you don't want to lose and do a clean Windows install. Any programs/applications will have to be re-installed after you re-install Windows.
Yep.... clean install is the way to go. Assuming you back up what is important to you it's never a big deal. Whenever I install programs be it MS Office or World of Warcraft I always save the install executables in a folder somewhere... for every program I have installed on my PC. Media files like pictures and videos are in their own backup folders... basically anything that doesn't come with Windows I have a backup for on a separate external HDD.

So when I built my new PC a couple months go it was as simple as:

  1. install fresh windows
  2. install all programs from saved executables/copy media files from the backup HDD to the new SSDs
  3. Enjoy new PC
It's amazing how many people don't want to do this considering how easy it is especially when the end result is a clean well running PC.

Read through that link.

When it asks 'what you're going to do', you select Custom.
You'll be presented with a list of all existing partitions.
Delete each one, until you are left with a single blank space.
Continue on...

And obviously, do this install with only ONE drive physically connected.
