One of my friends Computers is suddenly-dead, he listened music and suddenly off. He dont give life signs. I thought it was PSU, but there is light in mouse, as if it is running. What could it be ?
 
Solution
Still could be the PSU... the mouse LED is normal.. if you check this on a working computer the LED goes on even before you press the computer power switch, so that is not an indication of either good or bad PSU... the simplest way to know it trying the computer with a working PSU... borrow one to test the computer and make sure if it is the cause or not.
