THANK YOU! This has been driving me nuts since I built this computer a few days ago. It was so hard to find the exact issue I had. Like "How do I describe my issue in a way that will be easily searched in Google, but not so generic that every "keyboard beep" issue pops up. Ended up describing as "Every time I open a game the CTRL, ATL and SHIFT keys play toggle tones. First press makes an ascending 4 chirp tone then a second press makes 2 flat tones." in another forum. Time to go relay the fix.
