View Full Version : 870 Etreme3 No Video, Sometimes

09-01-2010, 05:25 AM
Hi Sean,

Just built (08-25-2010) a system with the 870 Extreme3 MB. Been running great and steady AS a Rock when it is running, but a few times since it was built last week I'm getting no video display -- only when first turning the computer on.

The monitor is popping up a dialog that it's not getting a video signal and switches to stand-by mode. I don't have an extra video card at the moment to swap out. The problem is intermittent but it has happened 3 or 4 times. I pulled the fanless video card out and reseated it but I knew that wasn't it, as the problem occurred again.

I'm hesitant to condemn the video card because I don't recall hearing the OS login music. Auto login to the OS is enabled and I would guess even without a video display you can still boot into the OS. Could be wrong though.

Everything powers up inside the case and it sounds like it is booting but it doesn't even get a POST screen. Watching the dr. debug codes, they cycle through a bunch of codes and finally ends with a FF code. The manual isn't any help as there is no code FF. Sorry I don't have a case speaker and wouldn't know what the beep codes were anyway. I could probably dig a speaker out of an old case if need be.

I've tried doing a reset, power off and on again and still no go. I can shut it down, wait a while and power up and it will boot normally. Heat isn't a factor as the problem happens on a cold boot.

Would you have a clue as to what the problem might be?

Thanks for any help.

I am having an identical problem with the same mobo and and raedeon 1g HD5770.

Has anyone had any luck in fixing this?

I don't feel like it can be a BIOS issue as it seems like I'm not even booting to the BIOS
