Windows 10: Start my computer

After the mandatory upgrading to my operation Windows 10 Home on 18/05/2019 my system it became too slow, especially at start-up.

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:

 

How to Get Started with a New Computer

You can't do any of this until you go through the initial login. After that the steps you listed are a good start though I use the builtin Windows Defender along with Malwarebytes Anti-malware Premium and Anti-exploit. #2 is key as far as I'm concerned. I backup every Friday using Macrium reflect Pro set for 1 full and 6 incremental.
