Hi, there is no video output, computer only keeps restarting and giving two short beeps. Twice out of many attempts the computer gave a screen where it asked for authentication, it asked for a 4 digit number to be typed in, but when I tried it then gave 2x4 beeps in decreasing pitch, like “fa - mi - re - do “ then again “fa - mi- re - do” which happened fast. Following this the computer shut down and kept restarting with no screen and two beeps again.
