    i have a computer a compaq sr1278an and sometimes it never turned on when i pressed the on button it would do nothing and at the back where the power supply on the computer is a yellow light flashes very fast constantly. This happened at random times and lasted about 3 days then it would turn on fine. its been about 6 months now and its still doing it does anyone know what this would be?

    My first thought would be a failing pw supply.

    Try another PSU in it and see if it works.
    I know that around here, a lot of the local tech shops will let me bring in my box and test out at PSU.
