Newb advice needed

Hey guys I'd like to download Mageia, I've never used Linux ever, so please tell me, is Mageia 8 good? When I use another operating system does it reset the PC memory? Is it good for games? (i have a Vivobook, it has 8GB of RAM, 235GB of memory, i7 of 8th Gen and the GPU is a GX230, if can help)

Yes, Mageia is very good. Mageia 9 is the current stable release.

Have a look here: https://wiki.mageia.org/en/Installation_Media

Installation media is here: https://www.mageia.org/en/downloads/

I would grab the Live media. That way you can test drive it first.

When I use another operating system does it reset the PC memory?

not sure what you mean.
Do you mean, does it replace your existing operating system? By installing the system, it must use some Hard Disk Drive / Solid State Drive space. You can erase completely your existing operating system ( simple install ) or install along side your existing operating system ( more complex install ).

as suggested by germ, try one of the Live .isos first by burning / flashing it to a USB stick / thumbdrive. They allow trial without making any changes to your existing system.
another option is to try it in a virtual machine - oracle virtualbox is a good example. it creates a virtual machine running on your existing operating system and so can be tried without rebooting your machine.

cant answer the games question, as I do not play games.
