Computer will not POST with Graphics Card Installed

Community Manager

Hello All,



I am helping my nephew trouble shoot a problem he is having with a new system that he is building. He has got an Intel H67 motherboard and a Radeon HD 7870 graphics card. The system will POST and allow him into the BIOS without the graphics card installed. However, with the graphics card installed the system will not POST. The PC just displays an error code of EB in the bottom corner. I checked Intel's website and it translates to either "Calling Legacy Option ROMs" or "Calling Video BIOS". I assume the latter is the problem because it seems related to the graphics card.



Things that I have confirmed with him so far:



1) The PSU exceeds the min power requirements for the motherboard and graphics card.


2) The PSU has a 6 pin pci-e power connector and it is connected to the card.


3) He changed the BIOS setting to use the graphics card in the expansion slot.


4) The fans on the video card power on when the computer is powered.


5) Re-seat the card in the expansion slot.


6) Disable the on board graphics card.


7) Computer will POST with another video card.


8) Updated the motherboard BIOS


9) Cleared the CMOS by removing the battery and unplugging it.


10) RMAed the card and the new one exhibited the same behavior.



I am totally stumped by this one and would greatly appreciate any suggestions.




Thank you in advance for any suggestions.

Is the problem the Radeon HD 7870 card is PCI Express 3.0 and the H68 chipset is PCI Express 2.0?

The may be incompatable features if the graphic card is not downward compatable to PCI Express 2.0.

Thanks for the reply.

I did some research into that and its seems that 3.0 cards will work in 2.0 slots, but only at the 2.0 data transfer rates. These links are pretty representative of the information that I found: PCI Express - Wikipedia, the free encyclopedia Will PCIe 2.0 x16 work with a PCIe 3.0 x16 card? - Yahoo! Answers

Tim, it seems like the problem that you are facing is related to compatibility. Sometimes we will get one of these cases when using an specific configuration the system will not recognize the video card. The EB post code usually shows while trying to recognize a device installed, in your case it will be the video card.

Currently I can only think of a possible solution and it will be to enable the expansion card text option in BIOS under the boot tab.

Also make sure that you are using the latest BIOS on this motherboard.

It was a BIOS update issue after all. My nephew told me he updated the BIOS, but he didn't. When I got to his house and looked at the BIOS version it was from 2010. Once I actually updated it to the most recent version, the motherboard recognized the graphics card right away.

Thank you for taking the time to help.
