Question Upgrading Motherboard, CPU, RAM and SSD


Mar 17, 2019
Hello everyone,
So I'm planning to upgrade my Motherboard, CPU, RAM and buy a new SSD. I'm switching from Intel to AMD and I don't know the exact steps I should take to avoid any problems with the old drivers.
I also want to keep my older HDD's (2 of them) and I'd like to know how to back up the documents from the old HDD.
And I want to install windows on the new SSD, so how do I remove the old windows from the HDD so I don't get any errors?
Do I need to fully wipe my old HDD before installing the new parts? If yes, how exactly If i have windows on it?
Sorry if these questions seem dumb, but I've never done something similar to this, so I'd like to do everything perfectly step by step. I've looked at some videos I found but none of them seem to explain in detail how to do it.
Thank You!
And when i reconnect the other HDDs how do I remove the windows from the old one?
You can view it through explorer and access files if you wish, or whatever you want.

What is the budget and in which country will you be purchasing?

Do you have a discrete GPU? Are you going to use one, or will onboard iGPU's be okay?

What are your main uses, and what are your goals if gaming?

What monitor do you have?
I'd start with something like this:
