hello all, I recently bought an Acer aspire timelinex 5830tg. Recently I have noticed that the function key for bluetooth/wifi and for volume control are not functioning. When I press fn and F2, the bluetooth/wifi is not prompting me but turning on and off automatically. The laptop volume control is also not working. please advice me on this.

Is there any way to reinstall the driver for keyboard so that all the function key combinations will work again?
