I am using a razer blackwidow ultimate 2014 edition, i play alot of games where i constantly hold down my "w" key. within the last week or so while im holding it down, itll just randomly stop, sometimes starting again and sometimes having to let go and repress the key to make it work again. ive tried updating the driver for it, using a different usb slot, my bios is up to date, cleaned the keyboard, ive tried all i know.
