IQ500 Black Screen at Start up

[cmcblue]

Powering on my touchsmart IQ500 desk top the sreen remains black (not even a blue HP BIOS / recovery page), system continues to boot normally behind the scenes as indicated by the default windows tone and led lights so the OS / Data and hard disk are still intact I believe (thank goodness). I shutdown the PC using "cmd" line instructions with appropriate switches in order to preserve the integrity of the data. PC shuts down correctly and powers off. I have tried holding the on / off button in for 30 seconds with the power disconnected but this makes no difference. I also tried the steps below with no success.  I recall Windows 7 giving me a message for a few days about the authenticity of my installed program but I disregarded it since I knew it was authentic (I was about to search for the product key). Any help would be grately appreciated......

1. Turn off the computer, and then remove the power cord.

2. With the power cord disconnected, press and hold the power button for five seconds.

3. Reconnect the power cord, and then turn on the computer.

4. Repeatedly press the F10 key about once every second for five seconds after turning the computer on.

5. Wait five seconds.

6. Press the F5 key. This restores the default settings of the BIOS.

7. Press the Enter key. This accepts the changes.

8. Press the F10 key. This opens the Save and Exit window.

9. Press the Enter key. This saves the changes, exits the BIOS, and then the computer restarts.
