Mobo Error Codes: 04 and A0

#1jakisthePosted 9/15/2013 1:55:25 PM
Might be O4 and AO, but at any rate, I have no idea what they mean for my specific board ( a GIGABYTE GA-Z87X-UD4H LGA 1150).

Everything on my machine seems to be working fine, but those error messages...what do they mean?

Should have them listed in the manual. First thing I'd do though is clear the CMOS.

If they asked how I died tell them: Still angry.

Well, the manual has no listing for 04, but the possibly-similar-looking D4 says "PCI resource allocation error. Out of resources."

I've only a GTX770 hooked up to the PCI port, and all my fans/cooling are working properly. Any ideas?

Do it the old fashioned way. Remove absolutely everything not essential to the PC booting and start adding it back a part at a time.

Hmm. Well, disconnecting my HDD prompted it to go to AO (A0?), which - besides saying that the IDE initialization has started - is apparently fine? Getting conflicting responses on that, looking around the web.

How would I clear my CMOS, and what would that do to my saved items?
EDIT: Nor do I know how to update my BIOs, and same questions as for the CMOS.

The codes aren't necessarily error messages, they are just telling you what part of the POST the motherboard is at. It sounds like your board passes the POST and everything is working, so you really have nothing to worry about.

you should have a cmos button if the mobo is gigabyte

Hmmm...fair enough. For what it's worth, it's not showing 04 after I unplugged/plugged my HDD, just back to AO. Guess it's alright?

Still, for the future: what would resetting the CMOS do in terms of stored data?

It will reset your BIOS settings back to default.

does a 770 need additional power in the form of a 6 or 8 pin plug?

is that plugged in?
