My CPU socket pins were damaged and so i bought another one it is the same motherboard i install it but my PC notice that i changed it.My original Bois that the mobo came with is 5.03 just like the new one. I update it the old mobo to the lasted bios from hp which is 5.23.

But since i changed it it revert it the 5.03 which is the new motherboard bios. So the i downloaded the bios from hp to update it but it says it does not meet the system requirements and i cant update it but some how it update it to 5.09 from some windows update package.

So is there anyway i can update it to 5.23 like i had it before?
I read on the internet that if you change you OEM mobo and replace it with another even if its exactly the same one it will not be recognize as an hp motherboard since my pc is an hp pavilion.

Anybody has this problem?

PS: i did not buy the new mobo from hp i got it off ebay. And the Bios from HP is for windows vista not seven. Also i already try installing vista again and updfate the bios from vista OS but no luck its not recognise as an OEM mobo.

An HP BIOS is unlikely to work on a non-HP computer, even if it's the same brand and model number, etc.

Get the BIOS from Asus. Pay attention to different revisions of the motherboard, if that applies.

As for Operating Systems, the BIOS doesn't care (or know) what you're running on the computer. The only hitch might be if you were trying to flash the BIOS from within Windows. Then the program you use to perform the flash might care, but not the actual BIOS file it is flashing. I would recommend flashing the BIOS from a bootable thumbdrive, if that's allowed by the flashing process.

PS: Your link won't work. List the exact model and revision number of your board.

PPS: You might have got a dodgy board off eBay. I'm not saying you did, so don't go complaining yet. But it's happened. First things first, let's try the other stuff. :)

I posted this here because it's easy to miss an edit:

I had to replace a bad board myself not long ago and Win 7 saw it as a new MB - even though it was the same brand, model, and revision. If that's your only problem I would just accept it. How does the system run on the replacement board?
