Hello, my computer is a Sony Vaio, and for the past times when i turned it on it randomly switches off, nd now when i switch it on, there is an orange light bt the screen is black and it makes a very loud computer sound? i am not sure what is wrong with it, its never happened before. I pressed all keyboard buttons bt no response nor is there any lights on the caps lock or num lock, i tried pressing all the keys such as Ctrl alt Delete bt no response. what could I do?
