    AV8 post code 9f

    I did search for this trouble, but the threads on it didn't seem to apply to my problem. The only thing I've done is replaced my Antec 430 PSU with a brand new Seasonic S12-500. No response. Led2 on the mobo lights up when I've got power to the PSU, but the machine won't even hickup. Could it have something to do with the new ATX spec of the PSU? They've finally ditched the -5V lead, for example.

    edit: connected the case speaker. I get a long beep followed by a short beep when I try to boot. No idea what it means, unfortunately.

    9F is standard, shown after uGuru chip successfully started

    The one long followed by short is according to original IBM standards, a motherboard issue.

    I don't really quite remember, but I think that mine also gave me a long-short, and it always seemed to work fine.

    I don't know why this would give you trouble just by replacing the PSU. One thing I remember seeing somewhere, is that you definitely need to have that -5v on that board, but I could be wrong.

    Who knows? I put the old Antec back in and the machine's running like it should again. Tested the Seasonic with my reserve machine that's got a 24-pin ATX connector and still nothing. Finally shorted the PSU's power-on pin and connected the cable. The fan doesn't turn. Seems it's a DOA power supply, not a problem with the mobo.

    First time for me. And I suspected some kind of mobo issue since a new and expensive PSU has to be working, right?That'll teach me to test new equipment before I rip apart a working machine!

    LOL! That's why I've been building PC's since I was 8~9 years old. You tend to learn quite a bit about hardware, and it'll save you some money in the end. Speaking of which, I have a few hard drives that need to be sold

    I've got quite enough HD space, thank you.

    As for the PSU a replacement arrived today, and I installed it. No problem at all except the case fans became very loud. The Antec PSU had a dedicated fan-out connector that also controlled the fan speed, you see. No recourse except making the case fans run on 7V. Surprisingly enough I found several guides on this site!

    My last build for myself I had a motherboard, video card and router all DOA. Yikes! Hopefully my next one for myself in 2008 will go better.

    9A and 9F are undocumented uguru codes that report something caused a forced shutdown. This can be a short or a power issue. As you know the bad PSU caused it this time.
