Get your MSI sorted out.
Check your internet connection and be sure you’re getting what you’ve paid for and that it’s suitable for the games you want.

If it’s a laptop you can’t upgrade it except ram (depends on laptop), so new laptop or Desktop upgrade the graphics card, usually it’s the graphics card or you might have low ram if not CPU, if you have a desktop and CPU, Gpu and ram are outdated I recommend you buy a “upgrade pack in which you can get a CPU, motherboard, ram and sometimes a GPU
