No startup after upgrade, only stuck in rgb only limbo.

[Cat427]

(Sorry for lack of hardware details, this site doesn’t work on my phone which is all I have right now) Hello. I recently upgraded my OMEN 40L GT21-0084 from my 3080 to a 5070Ti. After doing so along with a new psu the system turns on as soon as it gets power and will not boot. Just turns the light on the square and the rgb on my known working ram that I’ve had for a year. All my guesses go to a bad pc bios or outdated for this GPU and that it doesn’t know what it is since it doesn’t turn on any usb devices and will not show any sign of life besides the rgb. I’m lost and since this motherboard was cheaped out on by hp it doesn’t have a flashback for me to update my bios and it also has no debug lights (to my knowledge I’ve never seen one on or off). Any help would be appreciated as right now it’s just a color changing brick xD . Thanks in advance.

Hi @Cat427,

Welcome to the HP support community.

If your OMEN 40L GT21-0084 is not booting after upgrading the GPU and PSU, your OMEN 40L uses a proprietary HP motherboard (likely the Blizzard SSID 8918), and HP BIOS updates are tightly locked to specific hardware generations.

• The 5070 Ti is a newer GPU that may require UEFI GOP support or a newer BIOS microcode.

I was able to locate the BIOS F.35 as the latest one, and I was not able to find F.81 or other version.

To check the right version and to help you better, I would require the Pc serial number details.
 

Please help us with your HP unit serial number or the product number in a private message for further assistance.
