all my razor items suddenly have light turn off then on and I hear a sound in headset as it does it

Ok 2 days ago I noticed when playing a game my mouse, kb, headset stand, and not sure if headset did it but randomly all the lights cut off and I her like a windows sound like an action happened then it all cuts back on in like a second. It very annoying. I have uninstalled any extra mods in Syn and have turned off the the software and all other software and still does it...whats doing on!!! And it just did it and its only my kb and mouse
