So my issue is...just randomly out of the blue today, Windows started chirping the "new USB media inserted" over and over and over and over again, non-stop, surviving restarts. After it began, the first restart gave me a much longer than usual boot splash screen (where it says ASROCK). After a couple more restarts I went into the BIOS to just reset all to default to see if that would fix it, upon entering the BIOS I was greeted with extreme lag, only updating the screen every few seconds. Resetting the BIOS changed nothing. I even removed the CMOS battery and left everything unplugged for about an hour but that also did nothing. A few hours later I was told to update the BIOS, doing that might fix the issue..it did not, there was no change. I have tried unplugging all USB devices but the issue persists. I've also tried unplugging my hard drives but the lag in the BIOS continued. Unplugging the front panel USB also did nothing. In the hidden icons tray of Windows on the task bar, it shows a USB symbol that states "USB device not recognized" that does not go away when all USB devices are unplugged. Clicking on this symbol gives a pop-up message "The last USB device you connected to this computer malfunctioned, and windows does not recognize it" with a recommendation to reconnect the device. I hope that it isn't an issue that requires a replacement motherboard..but that hope is running out with every failed fix.
While typing this all out, the issue shifted slightly, the USB symbol in the hidden icons tray disappeared, and the sound changed to also include the USB device disconnected sound.
