Sorry, I should of told you to turn everything off which you control what uses the internet, like the bitorrent program, internet explorer, instant messengers.
Then do the NETSTAT /B
in the command prompt.
The task manager performance screenshot will give information saying how much memory your computer has, and how much of it is used up. It will say if there is something processor intensive which maybe overloading your computer. It may not be the case, but I cant tell without seeing it.
The netstat test is to check to make sure no spyware of adware is being broadcasted down your internet connection.
If the netstat test comes back empty, do a speedtest to see if its your internet connection.
I have also noticed that your connected wirelessly. If your using a usb wireless adaptor, it can also slow things down when the computer is worked hard. Eliminate it from the problem by unplugging it and plugging in the ethernet cable directly linking the computer and router.
