My Dell Optiplex 760 won't start but the start button blinks twice then waits for about 3 seconds and blinks once more before it repeats the process. The numbers 1 and 3 also appear every time the power button blinks. Can anyone tell me what it means. Already tried disconnecting the power cord and pressing the start button for about 15 seconds or more and nothing.

"Possible peripheral card or motherboard failure has occurred."
Sadly due the age I'd count on that motherboard being replaced but do try what else is on page 163.
