Need BIOS files: HP Pavilion 690-0020

[LR265]

Hi, I have recently upgraded the CPU in my PC (Ryzen 7 2700; upgraded from R5 2400G) and I am now getting messages that my CMOS checksum is invalid. When attempting to reset the BIOS, there is nowhere I can download files for my system.

When attempting a hard BIOS reset, the system goes into a loop of beeps that indicates the BIOS is corrupt. The PC still works largely but my PCI slots are not operating correctly. If anyone can link me to the BIOS files for my system so I can load them onto a flash drive it would be massively appreciated.

Hi:

According to your PC's motherboard specs it has a BIOS SSID of 8433

This is the latest BIOS update file HP has for your PC.

I have never tried to recover a BIOS so I wouldn't be able to help you with that.

You can run the file on another Windows PC and it will open to a screen that gives you 3 options:

Update the System BIOS on this device, which of course you don't want.

Create a Recovery USB flash drive to use on device with corrupted BIOS

Copy the BIOS image in order to use it on other devices.
