When did the error code appear? During POST? Was it a Windows bluescreen error?

 

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

80246002 Error from windows update

Every time I attempt to check for new windows updates, I get the error "Windows could not search for updates" and the error code 80246002. I've searched online quite a bit and only found a few links to Microsoft FixIts, and some commands you could run in attempt to clear it. I've attempted to simply reinstall windows, but even with a fresh copy I still have this error. Does anyone know anything at all that could help?
