An associate has a IQ770a model.
Some might say its an expensive door stop.
Judging by its weight you could use it for a mooring.
Anyway, it won't boot up without assistance.
Makes the startup type noises but the screen stays black.
A few taps on the F8 key & it either boots to desktop or goes to boot selection.
From there you can select DVD Rom or Hard Drive & its away.
A restart is the same.
Once it starts it seems to go well.
Have tryed a startup repair from Vista DVD, didnt find any problems.
Have re-insalled the motherboard & bios driver from HP.
No changes.
Googling the problem comes up with a few similar issues for this model.
Was wondering if anyone has found a way round it.

Since you flashed the BIOS, did you reset the settings then reconfigure the settings, then save them? And made sure the hdd is the bootdisk? Tried changing the CMOS battery?

From the HP site

Perform the steps in this document to resolve an issue where a screen has power but does not display anything.

Remove any media from the floppy drives, CD/DVD drives, USB ports, and memory card reader slots, and disconnect all non-essential devices (printers, scanners, external hard drives, and similar). Leave only the keyboard and mouse connected to the computer.

With the devices disconnected, restart the computer. If the screen now displays a picture and Windows starts properly, a device is preventing the computer from starting. See Updating the BIOS to resolve this issue.

If the screen does not display a picture or Windows does not start properly, select one of the symptoms that most closely matches the condition of the computer:

Show all | Hide all

hide

Screen remains blank and does not display the HP logo screen

Perform the following steps to reset the BIOS back to its default configuration:

NOTE:You can perform these steps even though the screen is blank.

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

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

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

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

Wait five seconds.

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

Press the Enter key. This accepts the changes.

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

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

After the computer restarts, the screen should display the HP logo.

If the screen displays the HP logo and Windows starts properly, troubleshooting is complete.

If the screen remains blank after briefly displaying the HP logo screen and Windows does not start properly, continue troubleshooting.

If the above steps have been tried at least three times and the screen is still blank (does not display the HP logo), the computer might require service. Contact HP Support for more information.

Screen briefly displays the HP logo screen

A blank screen and quiet clicking noises can be normal while the computer is attempting to change the display resolution or other display settings. If the screen stays blank for more than five seconds and then reverts back to the same display settings (no change is noticeable), then the screen was not able to enter into the new display settings.

Perform the following steps to change the display resolution:

NOTE:If you cannot select the display resolution, update the video drivers, and then repeat these steps.

Turn on the computer, and then press the F8 key repeatedly when the HP logo screen is displayed.

Change the display resolution to the low resolution environment as follows:

Windows 7 : Select Enable low-resolution video (640 x480) , press Enter , and then wait until Windows opens. Change the display resolution to match the default setting for the screen. For help on how to adjust the display resolution, see Changing Display Settings, Background Image, and Screen Saver in Windows 7 .

Windows Vista : Select Enable low resolution video , press Enter , and then wait until Windows opens. Change the display resolution to match the default setting for the screen. For help on how to adjust the display resolution, see Changing Display Settings, Background Image, and Screen Saver in Windows Vista .

Windows XP : Select Enable VGA Mode , press Enter , and then wait until Windows opens. Change the display resolution to match the default setting for the screen. For help on how to adjust the display resolution, see Changing Display Settings, Background Image, and Screen Saver in Windows 98, ME and XP .

The screen should now display Windows properly.

If the screen displays Windows properly, troubleshooting is complete.

If the screen does not display Windows properly, contact HP Support for additional assistance.

Thank you Speedy.
I had replaced the cmos battery which was flat.
Had also set hard drive as 1st boot.
None of those key combinations appeared to work on this system, or if they did, nothing changed.
One thing I have noticed, when the power is conected, the system tries to boot, as if the power switch is permanantly on.
I would suspect something is in the process of dying.
