My keyboard randomly stopped working, it didn't light up and it doesn't show up when connected to another pc. I tried the hard reset, holding esc, caps and spacebar and releasing when I plug it in and no luck. I ended up blowing on the USB and it worked until the next day. The next day I turned on my pc and it lit up just fine but after a few minutes it became unresponsive again. I've tried connecting it to several different USB ports and no luck. I tried multiple times hard resetting it, it just seems completely dead. And I'm not sure why. I can't even update firmware on it because my computer doesn't even detect it to update the firmware. Not sure what to do. Please help
