ProDesk 600 G1 Tower does not boot and shuts down within 2 seconds

ProDesk 600 G1 TWR
Microsoft Windows 10 (64-bit)

When I push the start button, the system will start up, fans are spinning, but after 2 seconds it shuts down. The white LED indicator below the power button stays ons. The aux LED on the motherboard is also on. Tried booting without any peripherals, unplugged all cables, even hard drives. But system will not boot. What is wrong?

I'm presuming, from your comments, that it doesn't stay up long enough to display any messages on the screen, right?

 

Most likely, the PC is experiencing a major hardware failure.

If you CAN, to find out the problem, you would need to be able run hardware diagnostics by pressing the Esc key repeatedly and then, when the HP Startup Menu appears, select Diagnostics (usually F2) and let it run.

If you can NOT do that, 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.

If you live in the U.S., here is a link to the HP Service Repair Centers:

If you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

Good Luck

I found out what caused the problem, the power button. When you push this button, it should click back, but although the button comes back, the switch behind it doesn't. It literally 'hangs', causing the PC to switch off again. I remove the front, cleaned the switch, and sprayed a tiny bit of WD-40 on it, Problem solved.
