At first the computer wouldn't boot and went to the recovery options screen instead, I tried the restore option but it shut down half way through. Now when I switch it on I just get the hp logo for a few seconds and then it restarts. It will not boot from usb either.

Welcome to the HP forums! It is a great way to engage, post questions and find resolutions by working with specialists in the HP community. As I understand the computer is powering on but there's no display on the screen, The computer turns off after a few seconds after it's turned on,
Let's perform the below steps:
Perform a hard reset (Click here for details)
* Checking the power source
* Power supply fan is noisy or having interference
* Power supply light does not turn on or power supply fan does not spin
* Testing the power supply separately from the system.
* Power supply light is on and flashes
* Ordering a replacement power supply
For more details on how to perform each step, click here.

Hi, thanks for getting back to me. I have tried some of the things you suggested, the socket it is plugged into works fine, the power supply light is on (not flashing) and you can hear fans start to move when you switch the machine on. The other steps involve taking the computer apart, mine is an all-in-one and I am not sure if I can do that - it doesn't seem to have any screws or similar I can remove and I don't think I am supposed to be able to service it. Do you think it is likely a problem with the power supply? I ought to be able to get a new one as it is under warranty still.

you are welcome. :) I appreciate the steps performed by you and certainly you have done a great job. Before we conclude that the power supply has gone bad, let's check a few things.
- When you power on the PC, does it stay on a blank black screen with the fan running or does it shutdown and restart continuously.
Let me know. Cheers!

Thanks for the information. :) Let's try these final steps and work towards a solution:
Reseat RAM memory and hard drive connections (All-in-Ones). Refer to user guide: http://hp.care/2fxRJmd.
Make sure the hard drive and memory module are securely seated inside the computer.
NOTE: This step requires opening the computer and should be performed by someone familiar with computer hardware and identifying internal components.
- Remove all external memory cards, USB flash drives, and CDs/DVDs, then unplug all cables from the computer, noting the location of each cable for later reconnections.
- Lay the computer face down on a flat surface covered with a soft cloth.
- Remove the rear cover. For detailed steps for your computer, go to HP Customer Support, type the computer model number and 'remove rear cover' or 'remove back cover' into the search field to find the document on this procedure.
- Locate the hard drive and memory modules inside the computer. You might need to remove the system board cover to access these components.
Figure: Examples of locations of the hard drive (1) and the memory module (2)
- On the memory module, spread the two retention clips outward until the memory module tilts up at a 45-degree angle, then pull it towards you to remove it. If there is another memory module, remove it as well.

- Reinsert the memory module (s) at the same 45-degree angle until it is seated, then press down until the retention clips snap into place.
- Remove the screw securing the hard drive cage, disconnect the cable from the hard drive, then remove the drive cage from the computer.
Figure: Remove screw (1), disconnect the cable (2), and remove the drive (3)
- Slide the drive cage back into position until it is seated, reconnect the cable, then replace the screw.
- Replace the rear cover, reconnect all cables, then turn on the computer to confirm if the issue is resolved.
If the issue still remains that it indicates that there's a hardware issue with the PC. You will need to contact HP phone support to explore the hardware repair options. You can reach phone support via www.hp.com/contacthp. Feel free to let me know if you have any questions. Cheers!
