No BIOS, no boot, No screen, no beeps - but power (fans and external lights)

[TMKroll67]

I was having some problems with my HD (Seagate). Ran Seagate repair but then Windows 10 had problems loading. Windows 10 began "automatic repairs" but then PC shut down. On power up, I get the fans (psu, processor, chassis) and external lights but nothing on the screen, no BIOS, no boot, no beeps. I have tried everything in HP online steps.

FYI - I have unplugged every external device, nothing. I have borrowed and tried a different psu, nothing. I can (and have) pulled all the RAM, nothing - no beeps on startup (which it should at least do).

Motherboard? Just happened to fail when Windows 10 was having a problem starting?

As I understand you are unable to boot upon booting to Windows 10. Don't worry as I have a few other steps to help you with this,

Since you have tried removing all the RAM and it does not beep, this clearly indicates the issue to be a hardware failure. I would recommend you contact our HP phone support for available service options. Please fill in the product details to get the tech support number.

Was able to get it up today by removing CMOS battery, powering on, powering off, replace CMOS battery and power on.

While I had it on, I made a backup of my files and created a recovery drive (USB). After such, I restarted and ran every HP system diagnostic test – particularly on Motherboard and Memory. Passed all, multiple times.

Powered it off. Won’t start again, same as yesterday.

Tried same procedure as before. Didn't help.

It DOES now beep (5 times in cycle) if it is started with RAM pulled.

this is unacceptable. what kind of trick  is this. asking to call the help centre isn't solving my issues, maybe is an option but not a solution

You really should stop answering these post if all your going to do is have the person send an email to support. We try and fix our devices on our own for a reason, whatever that may be. in the middle of a fix, you reach out for some help and you refer them to support. Not helpful....
