@Aswath7,

Good Day.  Thank you for posting your query in the HP community.  I read the post regarding issues with the desktop not powering on. I will be delighted to assist you here.

Superb description and spectacular troubleshooting and commendable diagnosis of the issue before posting. Kudos to you for that. 🙂

To assist you with accurate information I would require more information regarding this:

• Did this happen after a recent power outage or surge?
• Did you check with a different power cord and wall outlet?
• Please let me know the complete model# of the computer to assist you better.

For now, try these steps:

• Perform a hard reset on the desktop from this link: https://hp.care/2L9Lly8   

By following instructions from this section “Step 1: Performing a hard reset to resolve a blank screen issue”

Now check if the issue gets corrected.

• If it does not, power on then, perform all the relevant steps from this guided troubleshooter link: https://hp.care/2La21pn (HP PCs - No Power or No Boot Troubleshooting)

If the issue continues, then the PC has a hardware issue and needs to be repaired. If the PC is less than 3 years old, then you could contact HP phone support by following these steps:

HP Support can be reached by clicking on the following link: 

1. Click on this link – https://hp.care/2moMFSc
2. 2) Click on “Continue as guest”.
3. 3) Enter the serial of your device.
4. 4) Select the country from the drop-down.
5. 5) Click on “Show Options”.

Fill the web-form. A case number and phone number will now populate for you.
They will be happy to assist you immediately.

If the unit is under warranty, the manufacturer’s warranty should take care of it for you.

I am being honest about it by keeping your best interest in mind without beating around the bush.

If the computer is out of warranty for more than 3 years, then please contact any local Best Buy or Staples technician to get it repaired as service options with HP may not be available. This is because the original suppliers and manufacturers of the parts that are supplied to HP don't do so anymore and hence service options are not available.

Perform all these steps patiently as it is critical to resolving the issue. Good luck to you. I will keep a watch for your response.  

Let me know how it goes and you have a great day!
