Yes, you should try booting with SystemD. I can't swear it will definitely improve things but given your laptop's abysmal performance so far, it couldn't do any harm.do you mean that i have to try booting with systemd? would it be better?
if yes, what should i use 32 bit or 64. which version. xfce, fluxbox, ahs ...
Your laptop dates from 2017 so you do not need the AHS version of MX as it is squarely aimed at machines that are less than a year old. You should be using the 64 bit version and for best results you should use either MX's Live USB Maker configured to use GPT partitioning or Rufus on Windows again with GPT partitioning. If you want to try Rufus you might ask a friend, family member or colleague if you can briefly borrow their Windows computer (provided you don't have one of your own). On Win 10 and 11 Rufus is a quick install and a just as quick removal after the fact. You would of course have to copy the MX ISO onto a second usb drive beforehand so that you can take it with you to the borrowed computer's site.
Edited to add that you should do a fresh install of MX.
