Recently bought an Acer TC-605 from best buy. Spent a couple of days downloading and installing latest windows updates. When I first start using the computer, I would be working on something in ms office and listening to itunes at the same time. Audio would sound perfect for maybe 15 to 30 minutes, then it would distort afterwards anytime i moved the mouse or used the keyboard. Tried updating all drivers but did not work. However, when I pull the mouse's usb cord out and reinstall problem goes away. But 15 to 30 minutes later, problem comes back again. It would be kinda annoying reinserting the mouse usb plug every half hour. Will buying and installing a usb pci card fix the issue? I'm thinking maybe my onboard usb ports must be bad. Or is the issue with something else?
