Hi guys, I'm looking to see if I can get some help from here because I couldn't find any solution by searching google.

I recently got a new keyboard (cheap Chinese mechanical keyboard, I wanted to try blue switches to see if I liked them) and a couple weeks after I got it I noticed that sometimes when playing games, it's as if my key inputs would continue after I pressed them (i.e. "a" key would kept being input so I would go left and couldn't move any other directions.)

Of course, my first reflex was to change back my keyboard to my previous one (Razer Blackwidow Stealth) but the same problem continued and I still can't game at the moment.

The Chinese keyboard has polling rate options so I thought it might be that and tried plugging it back in and changing the rate but nothing works.

I haven't tried formatting yet, I would like to avoid it as much as possible (don't have a Windows CD right now.)

Could someone help please?
