We have a Compaq desktop that is a few years old and until recently ran fine. Then it started turning off randomly with no reasons whatsoever. The PC would not turn on for hours/days and would only finally do so after unplugging and replugging the power hundreds of times.
We replaced the power supply and that seemed to fix the problem almost instantly. The no booting issue happened once but only once.
Now the unit will not boot, and every time the power button is pressed the fans will spin up perfectly but the computer will not boot nor will the green light on the front switch light up. It also makes five consecutive noises like something is trying to start but ultimately fails to do so. Power down causes nothing to happen or the fans to spin highly.
We have tried plugging into the wall, power cycling by holding down the power switch, replacing the old power supply, all to no avail.
