Re: hp motherboard startup problem!!
Try this my friend... remove the cmos battery for at least 5mins.
while the battery is out, set the jumper settings to clear CMOS. few seconds only then put back to save CMOS settings.
after 5mins, put back the battery, plcae your CPU, sonnect your power supply.... can you see if your board uses an support power supply 12Volts for the newer CPUs. its a four pin colored yellow black wires. this has to be connected to your board. But if this models supported only by 20pin power supply then you will not find the 4pin additional power jacks for the board. anyway, try this battery thing to reset the whole system. it may work.

so does the VGA port on the rear of PC work. to a desktop monitor
yes, then the mobo is ok. but not screen.
i can make the mobo run on a table. vga connected.
with Fn+F4 toggled on and external USB keyboard, I can activate the external screen.
steps. are as follows. in proper order
1: remove that shorted huge battery, there. get it out of there.
2: make sure the power pack reads (VM) 19vdc at the jack.
3: new coin cell if voltage on its pins below 2.9v... yah?
4: get BIOS screens working FIRST. disconnect HDD and DVD drive. now.
5: go to 1 ram stick bank 0 (try 2nd one by self)
6: does the flashlight trick work on that CCFL screen,?
7: remove all modules from MOBO cept CPU and 1 stick RAM?
we call that the strip down tests.\
8: beep codes, or Caps lock key flash codes? what?
BIOS screens have to work, or mobo is dead.
has anyone been playing with BIOS doing crazy things like flashing it.>? yes, oops now you bricked it. then what (ask)

If the RAM is incompatible with your board then yes it would not allow a boot. Make sure your front panel power wire is plugged into the proper spot on the motherboard and retry. If it's the RAM then you will still have the problem. If it was the wire loose or in wrong spot then it should work. Hope this helps & please remember to rate my answer. Thanks.
If your video is running off the card then remove the cable and plug it into onboard vga. Then remove the card from the slot. That should solve it then you will need to reinstall drivers for video card. If your monitor is running from onboard video then you will need to remove the card then try turning it on.
First of all, your hard drive is what this computer needs to boot up. Try to see if you can POST, that is, only plug in power supply to motherboard with cpu and memory in there. Don't put any hard drive or other device into motherboard as yet. see if it reaches past post. If it does, then plug in hard drive and see if the problem occurs again. If it does, then the problem is the hard drive. But for now try reaching past post with only the bare necessary components for startup. Then let me know what happens.
