Windows 10: My computer cannot start

So recently my computer custom built keeps on closing after 5 seconds when I press the power button. It tries and tries over again. Its screen glitches a lot and also flickers. The BSOD Blue Screen Of Death error also occurs sometimes and when it does it is also glitched. When it somehow starts I cannot search nor open the windows button in the taskbar in the first 5 minutes.So how can I fix it? I would be very thankful if you can tell me what parts are not working properly or were assembled incorrectly.Thanks.

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.
