Sansa MP3 Glitch (Help Please)

I am trying to plug in my Mp3 player to my computer but when i do it makes the sound on my speakers of me plugging then unplugging it, which obviously i only plugged it in…
Then when i turn it on without it being plugged it, it turns on then off, but it does it repeatibly and i don’t even touch it…

Anyone ever have this problem or know how to fix it?

I think you need to call SanDisk Tech Support. You may have a defective unit.
