Quite a lot about black screens there as well.

Things you can try...
clonezilla; will clone the recovery partition, if there is one and you may be able to recover something that way.

Knoppix will probably boot and run and show your data to enable recovery.

Sainsbury (et al) sell Linux Magazines with cover disks. Worth a look.

Gparted Live to view if there are any partitions to recover.

Windows 10 .iso to attempt a reboot and repair, worked for me.

There is a theory that windows is running in the background and tapping the space bar and logging in absolutely blindly will trick/kick some new life into it. Power off and try F8 to go to safe mode. It is only theory.

Thank you.

It will still be USB though ......plus ca ne change pas , Try without the HDD ,and / or with a CD/DVD inserted a USB monitor adaptor will not help either I wouldn't think .

Correct, didn't help. Tried without HDD, with a CD/DVD (don't have monitor adaptor yet).

Also I found out that none of USB ports are recognising the keyboard (keyboard is working fine with another PC to rule out faulty keyboard). Numlock, Capslock, ScrollLock LED remain black at all times, not even a blink when i switch them on/off. So keyboard isn't getting power as such then I guess.

I have also tried powering down completely (i.e. holding the power button for 10 seconds or so, then holding it whilst the power adapter is unplugged to "discharge"). On powering up after that, nothing changes.

I have also tried hitting ESC whilst powering up, no success.

< depends upon what's wrong you say its a brick = new components .
Repair guy may well find its just a bad install .

I've downloaded HP Consumer Desktop PC BIOS Update to a CD. The CD drive spins when it gets a CD, but again no change to black screen, or a keyboard reaction.

I would be trying this next, as long as there is another machine to create it on.

I would use a USB and use the Windows 10 Media Creation Tool to create the bootable USB.

Then do the thing of holding down the power button to power off, then put the USB and see if it boots, perhaps with the HDD taken out at first.
Edit: Actually maybe leave the HDD in.

IMO software, drivers, hard drives and so on are not relevant here initially.

Any PC even with no hard drive should initially boot and start putting out some video in basic VGA mode so you can get to the BIOS.

Has it got any other video output ports such as VGA or HDMI you could try on another monitor or a TV if HDMI?

Is the keyboard OK, some BIOS's can fall over early on if no keyboard is detected.

It depends what is wrong on the machine, if it's some sort of odd software fault you've hit then a local PC shop would likely be cheaper . However if the motherboard has failed and the PC shop need to source it and fit it then I'd expect it to be far higher. Local PC shops here charge around £150-180 to supply and fit a replacement hard drive and that's a much cheaper part and usually quick and easy to fit whereas custom motherboards are usually pricey and generally take a good more time to fit.

From what you've said it sounds like there's hardware failure given you can't seem to get any response from the machine.

I still wouldn't replace hardware quite yet if it was my machine (but perhaps I'm just stubborn )

The default in Windows 8.x and 10 is to enable "Fast Startup", which means that the power button and Shutdown command are basically a form of hibernation, and not a true shutdown.

I believe sometimes the computer won't allow a cold boot into a BIOS setup because after a 'shutdown' (with Fast Startup) it has some marker to say the computer is hibernated, and therefore it doesn't allow a cold boot because it 'thinks' it would crash a session which is hibernated and still essentially running.

I think this is worse with Secure Boot and UEFI. (Not sure if secure boot will be enabled, but at that age I suspect it will be UEFI which means anything you try to boot from has to be setup for UEFI - a bootable CD or USB which works on an older computer may not work here, even when the computer doesn't have a problem.)

Having said that, I would have thought all the changes made (removing HDD etc.) should have convinced it otherwise by now.

Thank you for all your replies. I will be getting Windows 10 bootable USB or DVD (or maybe both just in case), and we'll see how it goes. So far no change in symptoms or behaviour of the PC.
