Blackscreen - computer whirring, lights on

Couple of thoughts

RAM - Remove the ram and try each stick in the motherboard seperately.
PSU - Try another power supply.

Try your monitor and cable on a different PC to rule those out. Unless it is a laptop (you did not state) then try hooking a monitor to it....
