Question about HP Computers & Internet
Despite that the green light is on, your PSU can be defective. You can follow the instructions found here to test your PSU. You can also use a use paper clip instead of wire. If your PSU starts when it's not connected to your mainboard you can make a second test, if you don't have a voltage meter, to see if voltages are OK. You could connect your optical drive to the PSU and see if your drive unit door is opening and it reads discs (without data cable connected). If your PSU will start (cooler rotation is OK, optical unit will work), then your PSU is probably OK. Next step would be to reset your CMOS settings, if PC will still not start then I would say your mainboard is defective. And, of course, proceed at your own risk.
If this is the solution for your problem, please rate my post, otherwise give us more details.

Replace your PSU then test all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty because a computer has to have an end to the circuit any fulty leads will lead to no boot up
