Ultimate Ability buttons not working on PC

[Draghi]

I have my buttons set to the defaults so "Q" uses my ultimate ability. But lately, it hasn't been working and I have to rebind it to another key and/or switch it back for it to work. But it's been happening more frequently. Even after I switched it to a key I never touch, it still wouldn't work sometimes. No, my keyboard isn't old. Outside of matches, the keys work perfectly fine.

Does your keyboard support anti-ghosting and what's the rollover count.

Not sure about the anti-ghosting thing but it's N Key rollover. I could stand still and press the Ultimate Ability button and it wont work sometimes.

Try binding it to your mouse.

Meanwhile, I bound mind to Alt so I could make Q a real ability button
