Changed NB to 3.0V still can't find why this cycles 8 times now before it shows post page.

3.0 V is too high. 1.3 V.

3.0 V is too high. 1.3 V.
Sorry yes 1.3V.
I'm getting worse as I get older.
Still the same. I took everything out except the ram and it still cycles 8 times before it post screens.
I wonder what it is?
I'm also having to send my Xbox back that has piXXed me off too!

Clear the CMOS using the steps in How To Clear CMOS (Reset BIOS) and do a hard reset as described in Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English). Then set the NB voltage back to 1.3 V. See if the issue is resolved with these steps.

I've tried everything now I think.

I even tried this:~

There is something you can try. Some bios types really hate major changes to the configuration when the OpSys fails to see changes in step with the user settings. This is particularly acute with a loss of the bios timeclock. As a note - when you're resetting the cmos manually by moving a jumper be sure to replace the jumper into the normal run position before rebooting. This is often overlooked "under the gun" of solving issues.

This type of problem does suggest some type of issue with power regulation across a set or subset of board components.. but.. you might want to try this first, in case its just an issue with a corrupt process held with a power state causing the instability.

Since you were trying various settings in the bios:

Remove all power from the system completely first:
1) A/C removed.
2) 24 pin main power supply removed from the board physically.
2a) All 12v rails (video & board) disconnected physically.
3) Bios battery removed
4) Cmos jumper in proper running position.

Next, Disconnect all drive and other attached devices EXCEPT, a CD Rom. Make it the only device the system can see.
NO USB devices, NO LAN, NO any device add ons. If you have other cards in the PCI bus. Remove those too.

Allow this to sit this way for around 15 mins or so to more completely drain all board caps of residual power.

- Replace the cmos battery and wait about a minute.
- Begin with the power connections for the mainboard & video, and only the CD Rom as the single device.

Next have your opsys CD ready to put into the cd-rom.

- Boot the system. Ignore any bios messages but do note them. If no specific errors are generated, then enter the bios and select defaults.
- Set the timeclock ONLY -- Important. Now FORCE a power off by holding the power button until it shuts down.
- Reboot the system and enter the bios. Did it keep the timeclock setting? If so, exit the bios and allow it to boot to the cd rom.
- Insert the opsys CD when prompted. If it runs up on CD and tries to error for missing storage device, then you can/have recovered the board.
- Next power down and add the Boot HD. At worse it says it corrupted. At best it boots cleanly into the opsys.
- Power off and restore the devices one at time, rebooting in between each attached device until complete.

If you see or have issues other than those noted, then I would replace the mainboard. I would see that as sign of a intermittant board problem.


Good Luck!
Found here:~ Won't boot unless clear CMOS every time, not battery - Asus - Motherboards-Memory


I think it's possible it could be the board! But, the problem is it does work properly 'once' after a full clear of the CMOS then reverts back to the fault.

Have you given ASUS a call to see if they have any experience with this problem?

I also am out of ideas and feel that it is likely the board itself causing the faulty POST behavior. Especially if you have re-seated all components at this point.

Yes, I have tried everything that I can try. Seems the only thing I can do now is call Asus. I'll try that next.

What's the one thing we never thought of during this whole exercise.
're-flash' the BIOS.
That cured it!
Thanks for your help in this problem writhziden it's been an honour and a pleasure working with you....

No problem. I should have thought of that... Glad you found a solution. I will remember this next time if someone has similar problems. I gave you rep for the good step.
