Windows 10: How do I get this off my computer?

I was on the Microsoft store and I see someone has hacked my account. I went to setting and I saw that there is an email address on the main account that I don't know of. It is on the main account of the computer and I want to get it off, but I can't because I need to sign into it, which I also can't because I don't know the password and it isn't a normal email account.Edit: If I factory reset my computer will I be able to get it off?

Does this computer build have compatibility problems? Opinions welcomed!

Lets start with what you're going to use this computer for, not what you want to put in it.

Rules/steps to building a computer (in chronological order):
First rule: Determine what your needs are.
Second rule: Define your budget.
Third rule: Pick parts.
Fourth rule: Review parts several times.
Fifth rule: Buy said parts.
Sixth rule: Build it.

You are on rule/step 1. Go through the list until you're done.

is it possible to hand build a motherboard?

Might I suggest you simply build a computer, making notes and taking pictures step by step. Most people (probably including your teacher) have no idea even where to start building a computer. You'll do fine, and if you get stuck we're here to help ya out! *Toast :toast:
