Hp pavillion all in one wont startup

[Paslode350s]

Computer was working fine, then my wife went to use it and startup stayed on the load up circle for a day. I shut it off tried again said automatic fix and now it is a blank screen with a working mouse icon nothing else. What can I do to get it to start. It has windows 10 not sure version.

@Paslode350s

Thank you for joining HP Community.

Could you please help me with the exact model name or the product number and the operating system of the computer?

Do you see any light on the computer?

Did you try connecting the computer to a different wall outlet?

Keep me posted.

I have a brand new HP 24-B016 All-in-one. I took it out of the box, plugged it in, and it won't boot up. There is power, I can see the light on the backside of the monitor 'on' where the power cord plugs in.

I have tried connecting to several power sources (all which work with my other computers).

I would appreciate any feedback/insight you have with this issue.

@SpeedyK I suggest you try the below steps to make this work:

Let's perform a power reset as per HP standards:

Ensure your device is OFF.

Unplug all the external devices (If any).

Disconnect the power from the computer

Press and hold the power button for about 30 seconds.

Connect the power supply

Press the power button to turn on your device and check if it works.

P.S: Welcome to HP Community 😉

Thank you for your reply!

Unfortunately, this did not work. Any other tricks up your sleeve? 😊

@SpeedyK I'm afraid that would mean there's a hardware malfunction on the device if that didn't work, I suggest you talk to HP support and discuss your options, follow the below steps to get started:

1) Click on this link - http://www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
