Well title says it all kinda, its a steelseries 6gv2.
I got it for free for helping a friend with something(not important) and lately its been acting up alot..
TEST PHRASE (no backspacing) This problemmm with my keyboard has bbeen fffuucking with mme alot and its annoying as balls, almmost at the point of throwing it away.. As youu can see the repeating of singlle letters and spaces are allllways the same.
Try a different port. If that doesn't help, try it in safe mode. If it works fine, then it's probably a software issue. If the problem persists, then it's likely a mechanical/electrical problem with the keyboard it's self, in which case it just needs to be replaced.
