Mechanical keyboard totally going crazy

[dzsamesz]

I have a mechanical keyboard with cherry mx red switches for two years. My problem started today. Sometimes the keyboard going crazy, the "u,i,o and r" buttons doesnt work, and many others are stuck, continuously hitting the ctrl + o, printscreen and other combinations. When i restart the computer, the key leds are lights up, but i am not able to enter to bios (maybe because of the stuck keys?). If i plug off the keyboard and wait 10-15 mins, then i plug it in, it works for couple of minutes or hours (now works for 30 minutes) but suddenly going crazy again. I tried my old keyboard, it works well. I tried this mechanical with my notebook, sometimes when i plug in immediately starts opening many windows media players, and doesnt stop hitting ctrl + o, but sometimes it works well. The [removed] is this?

There is a function (shortcut) that allows you to switch keys on Windows (idk why anyone want to do this, but u can do it). Google it and find the shortcut that allows you to go back to its original function.
