myLabel.Text = cpu.NextValue()

In case you end up with "0" (probably because you just created the PerformanceCounter and then directly used it) you need to add 2 lines as the PerformanceCounter need some time to work:

System.Threading.Thread.Sleep(1000)
myLabel.Text= cpu.NextValue

To Avoid that sleep you might want to declare the PerformanceCounter in your Class instead of your Sub/Function and set the probs in the forms loading event.
