When I open an application, play a video, run a game, or do anything on my computer, I get the worst high pitch sound ever... It's like someone drawing on a chalkboard with a razor every time I open something, or click on a hyperlink. Common sense tells me this is my cpu or gpu. But could my hard drive be at risk? Can I ignore this and blast some music while I play games? Is my cpu going too be dead weight if I do?
