I have a very strange problem. I've bought a new laptop - Asus G73JH with Windows 7 x64 Ulti.
Everything worked fine until I've installed so many apps that the system collapsed and I was forced to revert to an earlier restore point. I had to reinstall some drivers too.
Now, when the system is running, I'm hearing a very tiny silent beeping coming from the notebook case.
But it happens ONLY when the OS is running. It's definitely not the POST, nor a speaker. It is a constant beeping lasting from 3 to 30 seconds.. and happens randomly very oft, in most cases when the notebook runs on battery.
Do you have any idea what it should be?
Could it be the coolers? that it runs on some resonance frequency or something.. Or could it be a sound card driver? or maybe a catalyst driver?
net stop beep
on the command line. This will stop the service which is providing the beep through the internal speaker (if any). If it went away with that, it's the OS which tries to tell you something.
