Is this a pre-built system? It doesnt sound like it, since the parts are all decent, but if it is, you really should reinstall Windows 10. Some manufacturers load some garbage on the PC when they make them. If you did build it yourself, it still might be worth reinstalling Windows anyway.
First though, check what programs are running on startup, and disable any that you do not need to run automatically.
If you have upgraded from old hardware, it might not be enough to install the new drivers. You may need to use programs like DDU to completely uninstall any previous drivers you may have had installed.
