Hello, I am new in playing guitar and I own a Yamaha APX 500. My problem is, whenever I'm strumming , the high E string always produces a constant high pitch I don't know what to call it but it's really annoying and out of tune. It's my third time changing the string but still the same problem. Is it with the guitar, or is there something wrong with my strumming?

probably an intonation problem or string buzz. a picture would help
