My pc might has old hardware, maybe it has a max upload & download speed idk

Make sure that nothing Is running In the background (example: antivirus updating), and then do the speed test.

here's my internet on my pc, i don't know how my upload speed is higher than my download speed lmao

Do you have nVidia drivers? Unusual I know. When I used my PC before my internet speed was odd like that, and it turned out that for some reason the nVidia drivers for my GPU were interfering with the download/upload speed. Fix was to uninstall them completely and reinstall.
