    Q code 99 on cold boot, cycle power and everything is fine...?

    Hi guys, recently whenever I turn off my computer for a few hours and i hit power again, I get the initial ROG screen and it freezes there.
    So I have to hold down the power button until the rig shuts down and give it a second or 2 til i can push the power button again. This
    just started happening a week ago, and I just noticed the code showing 99 while frozen. Me confused, everything is always plugged in
    I'm not turning the psu off, so what gives?
    Thanks

    Code 99 is super io initialization so something in your hardware is failing to cooperate during the initial bootup sequence. If you can boot the second time around then I would try leaving the power to the computer on while you are not using it so everything stays energized while the pc is off.

    Ya but it's a total waste of power/$ - if I'm gone for a couple days i don't want the 3 230mm fans running at full speed for example lol. Besides, the rig was fine for 8 months, so I think diagnosing the fault is a good idea. The only thing I can think off is that I installed AI suite III again not long ago cuz it used to
    annoyed me, but I like the CPU fan profiles. I don't see how that could affect hardware at boot.
    Is there a chance a failing peripheral could be the cause, backlit usb keyboard is a bit twitchy sometimes, but it seems like a small thing, and it's been that way since my last rig..

    Hello WCPredator

    Code 99 is usually gpu related. First thing to try is clearing the cmos if that doesn't help try removing your 7970 and connecting to the onboard graphics and see if you still get the freezing.

    Hi Nate
    Thanks, I'll give it a shot. Gotta install the drivers.
    The card has always been a bit wonky, worsening slightly with time, but it's still functional.
    l've been meaning to RMA it, but last time they said they might give me an R9 280 and I wasn't havin that noise. Push comes to shove I can force a 280x. Now would be a good time to RMA while they fix arkham knight...
    Do you think it poses a danger to my board?
