Problem

Hello, my HP Pavilion 590-0018UR computer starts blinking and beeping 2 big times when I turn it on, and then it beeps 2 small times when I turn it off. What should I do?

Hi:

According to the troubleshooting guide at the link below, it appears that your PC has a corrupt BIOS.

HP Desktop PCs - Computer beeps or a light blinks during startup | HP® Support

he red light blinks twice, and then two, short white light blinks (2 long red, 2 short white)

This condition indicates that the main area (DXE) of the BIOS has become corrupted and no recovery binary image is available. It can also occur when updating the BIOS.

1. Allow the system to complete its updates and any changes.

2. Attempt Sure Start Recovery if the updates are not installing as expected.

   The only suggestion I can offer would be to make a USB BIOS recovery drive on another PC and use that to try and recover the BIOS on your 590-0018UR PC.

   Watch this video for how to do that:

   Your PC comes with the HP AMD 'Sunflower' motherboard with a BIOS SSID of 8433.

   Below is the link to the latest BIOS update HP has for that motherboard (F.60):

My power indicator is blinking white.

There's no guide for that, so my assumption is if there are two long blinks and two short blinks then it is the problem that is described.

I'll try to figure it out
