Laptop making a constant beep noise
Just got this laptop like three days ago. But the laptop makes a faint beep noise. The noise is made when I plug in the USB hub. So then I decided to take of the usb hub and just plug in the wireless mice receiver and the noise came back. Now when I plug in the Webcam there is no noise. However, when I take everything off there is a very faint rhythm of long beeps. Please let me know what the problem so I can fix it. I really like this laptop but I have issues with the beeps
This is what I have: Asus U35JC-A1, 13.3" @ 1366X768, i3-370m @ 2.4GHz, 4 GB RAM, Geforce 310m/Intel HD (Optimus), 500GB 5400RPM HDD
Thank you.
