Having problems with your HP Computer Processors ?

Push the on button and nothing happens

\015 I assumed bad power supply. Replaced same results\015

Answers :

I believe you are using a new power supply now.
\015\012Before you start, first check if your Power button is OK.

To do this, first unplug the power cord from your PC.

Remove POWER-Button connector (with black/white or blue/white wires) from you Motherboard
\015\012Remove RESET-Button connector (with black/white or blue/white wires) and put it on the place of POWER-Button. (polarity for these buttons is not important)
Plug the power cord back and press RESET.
Does it change things ?
\015\012If it starts, then your Power-Button is broken.
If not, remove the power cord and then put te POWER-Button and RESET-Button on their places on the Motherboard.
\015\012Now do the following:
\015\012(please remember the position and polarity of all cables/items you remove/unplug, Use Digital camera if necessary). Be patient, don't hurry!
\015\012- Unplug the power cord.
- Press power button few times (power cord is unplugged).
- Remove the Battery.
- Unplug the Monitor cable and remove VGA card.
\015\012- Remove RAM module(s).
- REMOVE any PCI cards(Modem. Lan, Audio etc.).
- Unplug any HDD/FDD/DVD cables from the Motherboard.
- Unplug Power from all your HDD/FDD/DVD devices.
\015\012- Put the batery back (be careful to the polarity)
\015\012- Put the Computer power cord
\015\012- Turn on your PC.

Is the Processor Cooler running ?
Are there Beeps from PC Speaker?
If not, then your Motherboard is broken !

If there are some beeps, then your Motherboard is OK, but some component(s) is broken.
\015\012Turn Off your PC by pressing the Power button for about 4 sec.
\015\012Unplug the power cord and press Power button few times.
Put your VGA back, and connect the monitor cable, too.
\015\012Put back ONLY ONE memory module (if there are more).
Connect the Power cord and press Power button.
\015\012Do you have a picture now ?
Are there Beeps from PC Speaker?

If you have a picture, put back all other memory modules and PCI cards, connect Data and Power cables to your HDD/FDD/DVD units, but ONE at TIME.
\015\012Do not connect and put everything back all at once!
After each change, see if there is a Pcture and (one) beep.
\015\012It needs some time but that's how you will detect which device/cable is maybe broken!
\015\012And remember:
Before you do any change, AALLWAYS do that with power cord unplugged and power button few times pressed !!!
\015\012If there are Beeps, try another memory module.

Again if there are still beeps, you have problem either with your RAM or VGA.
If there are infinite long beeps, than it is your RAM.
If there is one long and many (8) short beeps, then it is your VGA
\015\012Replace it!
