[SOLVED] Keyboard randomly stops writing/or automatically types last letter i typed 100 times

[Changedman223]

All of sudden, my keyboard started behaving pretty weird, its new, bought 20 days ago, and when i type something it can either stop typing or type the lastttttttttttttttttt (THIS) letter 20 times, for some reason it just started happening, i didn't download anything in last couple of months, im playing league of legends so i dont need anything else, and when i do i kinda cant cast abilities in time, so i need help resolving this issue.

Test it on another computer, if it does the same thing return it.
