Well, i would probably use it to set up a nice Linux Developing Environment.

Yeah i know about mechanical Keyboards, i have one from Cherry and a Blackwidow myself. But he was the one referring to rubber domes, so i just went with that as a fact and didn't look up the keyboard myself. I'm Sorry.

maybe the contact under the dome has gone lose or something like that?

Yeah it's when the signal from the key gets repaeted or it's just stuck,in your case i would say it's stuck in some way since if it would be the signal it would stop with unplugging, maybe clean out your keyboard and check the key? Also tapping it should be the qickest fix as the guy above said but if the key is stuck in a way or there is some dirt in it the problem will reappear.

Will try reinstalling, thanks. But i don't think it can be because of the Headers since my Mouse and my Keyboard are connected to the ports on the back of the mainboard.

Sometimes Randomly my Mouse and Keyboard (also Gamepads and stuff) stop working for a few seconds also i feel like the Audio Volume on my Headset drops when this happens, otherwise theres no visible problems, games work fine there is no (noticeable) FPS slowdown when it happens, also i think the fans work normally but i haven't really watched the fan speeds. -Win 8 64 Bit -Z87-Expert (bios up to date, couldnt find the version number right now...) -i5 4670k (no oc although i had it at around 4ghz for a while) -Evga Geforce Gtx 770 Superclocked (Is at non Superclocked speed,didn't need it) -Avexir Blitz 1600 2x4gb (green or i think it's called gigabyte sniper because it fits with the theme of that mainboard or something) -Superflower Leadex 80Plus Golden 750w I don't think my hardrives are Relevant for this problem but if you think it has something to do with them ask me and i will look up wich one's i have exactly. Thanks for your time. -Seamus9999 Edit: Stupid me forgot Psu..
