Keyboard glitching

Every time I press keys it adds symbols and numbers for example
every time I press the W key instead f just W it types W*
same for w Q and O every time, I press q it goes to the start of the sentence and with O it goes back a space
how would I fix this?
 
Uncertain as to cause. Try another keyboard in same USB port - change? Try in another USB port - change? Check Device Manager to see if error alert on keyboard, USBs or human interface - describe all found.
