My HP Pro 3500 displays nothing on screen. However the CPU and Chasis fans are spinning very fast. What could be the problem.

Those fans do spin at 100% speed (and maximum noise) until the POST completes, and the motherboard has determined that the temperatures are low-enough that it is possible to "throttle-down" the speed (and noise) of the fans.

 

If it does not POST, you get the symptoms you reported.

 

Power-off the computer.

Disconnect the AC power.

Remove the RAM, and re-insert it, to "re-seat" it.

If you have an add-in video-card, remove it, and re-insert it.

Reconnect the AC power, and try again.

 

If nothing, then power-off, disconnect the AC power, swap-in a different power-supply, and try again.

 

If nothing, you could have a dying motherboard or a dying CPU.
