    Default AsRock Extreme 4 MOBO NOT Completly shutting down after BIOS update

    I updated the BIOS in the Asrock Z77 Extreme 4 MOBO (using the instant flash feature) a few days back and since then the computer is NOT shutting down properly.

    Windows 8 shutdown but then the fans, CPU Cooler and the Graphics card stay ON. The graphics card fan reaches full speed after windows shutdown.

    I have replaced the PSU and disconnected the other components one by one to make sure that the problem is in the MOBO.

    This was a perfect board that was working great till the BIOS update.

    Any help? Thanks in advance.

    Specs:
    ASRock Z77 Extreme4 LGA 1155
    Win 8 x64
    i5-3570k
    16gb DDR3 1600 RAM
    Cooler Master V700 PSU
    H100i CPU Cooler
    HIS 7870 Graphics card

    Hi, I tried the CMOS reset. I even took out the MOBO battery just to make sure but still same problem. I do NOT have any overclocking and everything is default in BIOS.

    I assume you mean you flashed to version 2.90?

    I have your board with the same CPU, and 16GB of RAM, and use Win 8 64bit. I just flashed to 2.90, and am not having the problem you are. In my case, I had to reset quite a few settings that I need for my PC's configuration.

    I'm really unable to give you an answer to your issue, since it seems some users of our board have this problem, but I never have on two PCs that use this board. It sounds like your PC is entering S1 Sleep, but I don't know which default value may cause that.
