I’m going to mirror what No Time To Play said – you need to know what kind of game you want to make first. If you want to make an interactive fiction game, Twine would probably be fine. If you want to make a JRPG, then RPG Maker would be a good fit.
There are a huge number of engines out there, and some of them are hyper-specific to a particular genre (like those I just mentioned), and some of them are generalized (Unity, Unreal and Godot are great options). Using a non-specific engine requires more abstract learning though.
To answer your question about your hardware, that will undoubtedly limit what software and techniques you can use. I am sure you can find something that will work but it will still probably require some learning.
EDIT: Oddly enough, I was poking through a Kenney bundle and found a PDF called “Getting Started with Game Development”. He suggests Construct 2, Game Maker: Studio and Stencyl as pretty easy to learn. He also mentions Löve – I found this to be pretty easy to learn BUT it is a framework, not an engine. You’d need to learn Lua.
Of course, any and all of these suggestions may or may not work with your hardware.
