All of a sudden I had a blue text-screen avoiding a start-up, but now no start at all anymore. A tiny red LED shows on the main-board (an ASUS P8P67) and goes off after a couple of seconds and the chip-ventilator stops. The (empty) CD-drive makes a starting-noice and stops, the screen-light flickrs only. This continues untill I switch-off the computer entirely with the main-switch.
As I'm a dummie I'm completely lost!
Thanks in advance for a hint!
