Some PCs beep when close to overheating. I don't think that's it unless you know that at noon you place your laptop on a towel or soft surface that blocks vents. Just want to cover another cause we run into.
About a month ago my HP laptop started beeping for 2 minutes every day at noon. No message pops up. Alarms & Clocks app was not set but I uninstalled it anyway, also ran Malwarebytes and CCleaner registry fix. Haven't recently installed any new programs or downloaded anything that looked suspicious that I'm aware of. Please help.
