I have just clean install my laptop running Vista 32-bit after major hard drive corruption. Sometime while working on the computer (like clicking on or exit out of a program/folder), my laptop will give a random sound like when you plug in a new hardware although there's definitely nothing plug-in at the time. This really anoyed and one time my screen will flicker and then blank for a moment and then come back.
Do anyone know what wrong with the system? Please help me with this problem
