It started about a week ago, quite loud one second ring that repeats for about 15 minutes starting at 12:15 PM every day. I ran Malwarebytes on both HDD's - Nothing. My Oregon Scientific WMR 968 weather station has no alarms set. DELL is behind hardwired router firewall and running AVG anti-virus. Nothing new running.
Rings from inside the box, rear, bottom. Just annoying.
Can this be a low battery alarm?
