HP All-In-One - Loud beeps (3 of one tone and 2 of another), black screen

HP Recommended
HP All-In-One - hp c0053w

Upon start-up, computer beeps very loud (3 of one tone and 2 of another) and the screen is black. Goes through about 4 cycles of beeps before stopping. White light is flashing. No lights on the keyboard.

Any suggestions? Did nothing to the computer. Perhaps there was an error during an update?


Of note, when I opened it up I notice the fan does not spin when it is powered on. I also see some black "charred" looking substance on the copper tube piece coming off the fan.

Depending on the age of the PC and BIOS vendor...



Exactly as Fanordi has stated.
