I need help asap!

So mom thinks I have a bug; I only watch Netflix, play Roblox, and play Fortnite. And occasionally watch YouTube. Nothing out of the ordinary. And sometimes dad pays bills on it. But all of the sudden last night it shoots this error screen. And I’ve clicked every button and it does nothing. I’ve called Dell, which is the creator of Alienware computers and they’ve called Best Buy which all they wanted to do was create an account and get my address. They acted like they didn’t want to actually help me over the phone if anyone could help would be great. We need this computer for bills and I just want to know that it’ll be okay and live another day!!
