computer won’t boot

[mysteriø]

okay so every time i open my computer and turn it on, it shows a grey screen with a short dash blinking in the top left corner for a few seconds, then switches and shows the hp logo for another few seconds, switches to a grey screen again without the dash blinking for a couple seconds, then turns to a black screen for yet again another few seconds, then repeat. this happened after i attempted to reset it and the computer failed to fully reset. i then accidentally unplugged the ac adapter while it was loading. i plugged it back in, and then that’s when this loop began. i don’t know what to do. help!!

Hi @mysteriø

Welcome to the HP Support Community. 

To better assist you - 

1) May I have the exact model name of the product? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc.

2) What's the operating system installed on the computer? 

While you respond to that, try a hard reset - 

1. Shutdown the computer. 
2. Unplug all the Adapter and peripherals connected. 
3. Remove the Battery. This step may not be applicable if the computer was shipped with an in-built battery. 
4. Press and hold down the power button for 15 to 20 seconds. 
5. Plug-in the Adapter and put the Battery back into the computer. 
6. Try to turn on the computer. 

If the issue still persists, try initiating the system recovery - 

1. Shutdown the computer.

2. Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.

3. Press F11 once for System Recovery.

4. Choose the Keyboard Layout.

5. Click on Troubleshoot.

6. Go to Recovery Manager and click on System Recovery.

Note : System Recovery will delete everything that you had saved or installed on the computer.
