Windows 7: New build, been fine so far, now debug codes and no VGA signal

New build, been fine so far, now debug codes and no VGA signal

I usually leave my computer on whenever I leave to the store or something, then come back and everything is fine. This time, I came back and I see a red light coming from my computer; a debug code. I turn on the monitor, no signal and my monitor reverts to orange (power saving mode). The code that was on the Dr Debug was 32.

As of now, I don't know what that code means. I then proceeded to turn in off/on and off/on again and I got code A9, then it was stuck at A2. I cleared the CMOS, twice, don't know if I should have done that, now it reads A2 for awhile, then it's stays on D6 for a while which is something with the VGA, then the Dr Debug turns off and the hardware seems to be running like normal, except there is no video signal. I don't have a video card, I'm running on the processor's integrated video, and I have no idea how to fix this. Help would be greatly appreciated. Oh, and I can't access the BIOS because the screen doesn't even turn on.

My system specs are listed below and are up to date.

Referring to page 42 of your manual (download from ftp://europe.asrock.com/manual/Z77%20Extreme4.pdf if you haven't got it handy), it gives a list of the Dr Debug codes.

The codes that you have got are:

0x32 CPU post-memory initialization is started
0xA9 Start of Setup
0xA2 IDE Detect
0xD6 No Console Output Devices are found

This could possibly indicate a corrupted BIOS and/or a memory problem. Clearing the CMOS should have taken care of any incorrect configuration data, but it can't take care of a corrupted BIOS itself. Assuming that you used the jumper method (you did replace the jumper in its original position?), try removing the CR2032 battery for a short period, about 15 minutes should be enough. Any difference in booting now, any other codes displayed by Dr Debug?

Do the NumLock, CapsLock, and ScrollLock keys work on your keyboard, and do they toggle the indicators? Is the monitor cable correctly attached, or do you have access to another one to eliminate that? If your monitor supports other input methods, try the available alternatives. VGA is an ideal one for trouble-shooting purposes.

As one of the error codes you have got relates to IDE Detect (0xA2), disconnect all drives from the motherboard. Again, does this make any difference to booting and the error codes displayed? If you now get a message on screen along the lines of "Operating System Not Found", then it could indicate a drive problem, with the BIOS hanging at that point.

Does any of this help? Please post back so that we can further help you.

I actually have a clear CMOS button on the I/O panel which I used. I have removed the battery for 15 minutes, then replaced it and nothing seems to have changed.

I have a wireless keyboard, and it doesn't have any indicators for numlock, capslock, or scrollock.

Yes, it is correctly attached.

Both my monitor and my motherboard have DVI I/O's, but to my knowledge I don't have a DVI cable. I do have a DVI/VGA adapter but it's a DVI-I and my motherboard has a DVI-D output.

I have disconnected the one hard drive I have, and rebooted, but everything still seems to be the same, no 'OS not found' errors, just the same code A2 for a brief period, then stuck at d6. This, I guess means that the hard drive is perfectly fine.

I've looked around some, and most people who get the d6 error 'No Console Output Devices are found' find the problem to lie in a faulty graphics card.

ASRock details Dr. Debug code d6 as 'The VGA could not be recognized. Please clear CMOS and try re-installing the VGA card. If the problem still exists, please try installing the VGA card in other slots or use other VGA cards.'

But I don't have a graphics card, I use the integrated Intel HD 4000 Graphics in the i5-3570k that I use. So how is this possible? Maybe a bad VGA Cable? I could try connecting my computer to my TV via HDMI. (My monitor only has DVI and VGA).

It's certainly worth a try. It is not unheard of for a graphics cable to become faulty, either through damage to the cable itself (one or more wires broken) or to either of the plugs (pins bent/missing).

Okay, so I have now tried plugging my HDMI cable from my computer to my TV. I still get the d6 code and no video output. What else could this be?

From what I've read on the internet, this seems to be some sort of motherboard problem. If I could fix this without returning it, as I'm pretty sure I'm out of warranty for both the retailer and the manufacturer, that would be fantastic. There doesn't seem to be much help for me here btw.... odd. Ideas? Suggestions? Anything would be greatly appreciated.
