If you never ever see anything at all on the screen then it's pretty safe to assume you have a hardware fault. Nothing wrong with trying the Linux idea though just to make quite certain.

Always pop back and let us know the outcome - thanks

Are you sure the power adapter is OK; delivering the correct volts? Can you check it with a volt meter?

How do you know the hard drive is working?

What light is flashing "amber"?

you might try this sometimes it will clear the memory and it will work again.removes battery remove power cord adapter and then press power button for 30 to sixty seconds with nothing connected then release put battery back in then connect power .see if it will boot.sometimes this needs to be don 't more that 1 time to get it to work.but that has saved a lot of laptops .

power adapter checks fine, can hear hard drive spinning not fan, amber light for low battery.

Low battery indication, no fan activity, and drive can be heard to spin... and yet power adapter checks out OK (correct voltage out). Any chance you can borrow a suitable power adapter to check the system with...? I'm not totally sold that the adapter you have is as good as it may appear...

Power adapters fail a lot more than many realise; often test OK "off-load" but volts drop when "under load".

I have now tried to clear the memory as suggested, but no response, tried 3 times just to be sure.

does "anything" show on the screen - even if only briefly?

What happens if you were to boot up with Linux disk - Ubuntu for example?

Ubuntu.com - download the free ISO; burn to a dvd; boot with the dvd...

I'm assuming this is a laptop (there is a Del 520 tower too). If the hard drive is working and it "seems" as if it's booting up then a problem with the connection to the screen or even the screen itself is possible. A ribbon cable connects between the motherboard and the screen and sometimes the connectors at either end work loose. Also when it appears to have finished booting move the lid gently from fully open to nearly closed. If at any point you suddenly see something on the screen then it is likely that the cable is faulty around the hinge area due to movement (although it could still be one of the connectors).

There are various other possibilities but the above is quite common place.

Not sure if anyone suggested this but, have you tried an external monitor?

Can't see any such previous suggestion - definitely worth a try.
