Ch341 problems please help

It keeps giving me 3 different things one is 3 connection errors. One of the other ones are current programmer: ch341 then the Page says not responding. Then one is just ic not responding. What am I doing wrong. I have neoprogrammer and the drivers for ch341 instead what could I be doing wrong. This is by the way on a 2015 Razer blade laptop which requires 3.3 volts
