Computer will not turn on... no noise when power button is pressed

[nanyajelp]

Tried to turn it on, no go.  Unplugged everything, pressed the power button for over 15 seconds, then plugged it in (the little light above the power turned on), pressed the power button, and not go- no noise, no movement.  I have two of them so I used the power supply from another computer (same exact) and the same thing.  Used different outlets, and still nothing.  Pls. HELP.

Thank you,

rob

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number

Case number and phone number appear.
--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
https://www.service-center-locator.com/hp-hewlett-packard/hp-hewlett-packard-service-center.htm

If that link does not provide the results you want then use the main HP link:

Good Luck

Thank you for your response.  I took the computer to MIcroCenter (I believe they are an authorized HP repair center) and they did a diagnostic.  They say that the Mother is bad and needs to be replaced. $450!  The computer was only $600 (Costco). 2 months out of warranty!!  Is there a different, cheaper, used motherboard I can use with the same form factor.  There are several online (older model) that does not accept my Intel chip.  Is that all I have to worry about- the Chip compatibility?  Is there are any other compatible boards out there to the Krabi-UF   L11016-601?  If so, please help me find a cheaper solution.  Thank you again.
