Since you specifically mentioned gaming and streaming, a great option for you as a beginner is Nobara.

It is built specifically for gaming and streaming and has many of the tools pre-installed and makes DaVinci Resolve setup really easy (is a challenge otherwise lol). It’s based on Fedora, heavily modified kernel for performance and makes Fedora ready for gaming out of the box (which is why I discourage Fedora for gaming as a beginner, that takes a lot of set up for gaming and nvidia).

Nobara is also great for beginners because it comes with some brilliant GUI options - apps that let you click onto the specific drivers, packages you might need and the Welcome app includes options step by step of what to install. You will mostly use such an app for updates, so it takes away a lot of the fear of the terminal (but you can still use no problem). It also includes some great options for streaming apps you’ll need.

Also comes with KDE as its main suggestion (Nobara version of it or pure KDE, very little difference, basically the same with a few extra Nobara icons added i think). KDE is a fantastic DE, the workflow is similar to Windows out of the box and you won’t be unfamiliar with it, great one to start with. Plus its so customisable so you can get it looking very different from windows if you wish (which i did with mine).

They have a great Discord too if you wanna ask any questions about specific games or issues. It’s basically Fedora but gentler learning curve and everything you need ready to go out of the box

I bought a laptop very similar (same model group but from the year after) to this just before Christmas for my niece. Got it 2nd hand, as my brother was just looking a laptop that she could browse on and maybe do some homework.

I refurbished it and got it cleaned up and I tried lubuntu, xubuntu, linux mint xfce and one other (forget now). Same thing kept happening. Would simply freeze when trying to boot them. Had removed Secure Boot too.

After couple days of trying I ended up giving up and going with a Windows 10 LTSC IoT version from Massgrave for her.

Wish I had better news or something more productive for you. Sorry!
