Does the desktop hang from two browsers and a messenger?

Question

Google Chrome

Here is such a comp, old enough, but Windows was reinstalled 3 months ago. Desktop hangs when I press RMB. spin around for a minute. I usually launch Yandex and Google browser and telegrams. Oh, and conductor. why does it hang? the main thing is when the download is spinning on the desktop, other applications calmly switch and work, even the explorer and access to the PC is through it. although when switching to the PC is loading. tell me how to make my laptop work faster.
