No restart

[PoppaJoe1873]

I just updated my son's desktop computer. The computer will not restart after updating the BIOS. All I get is a blinking white light and it blinks every 8 seconds.

@PoppaJoe1873, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

A blinking white light every 8 seconds on your HP Pavilion 590-p0030 after a BIOS update usually indicates a failed BIOS update or corruption, leaving the system unable to POST (Power-On Self-Test). Here’s how you can recover it:

Basic Hardware Reset

Unplug the power cord.

Hold the power button for 15 seconds to discharge residual electricity.

Disconnect everything except:

Keyboard

Mouse

Monitor

Plug in power and try turning it on again.

BIOS Crisis Recovery (HP BIOS Recovery)

Your HP PC has a built-in BIOS recovery feature.

I suggest you refer to this guide: HP Notebook PCs - Recovering the BIOS (Basic Input Output System) | HP® Support

Also, I suggest you refer to this guide: HP Notebook PCs - Computer beeps or a light blinks during startup | HP® Support

I hope this helps.

Please feel free to reply here if you have any questions or if you need further clarification on any of the steps. 

Take care and have a good day.
