yesterday, when I was browsing on the net, my computer starts beeping. I don't really care about it at first, but as it get more and more frequent that I must get rid of it! but I don't know why is there a beeing sound, it is given off from the case, it is a short beep, it beeps whenever it wants to, I have no idea how to or how not to make it beep. one thing is that, when I am in the game, and if it beeps, everything will just stop for a second and then resume, wht's wrong with my com. ?
