    Default Asrock Z77 Extreme4 does not detect GPU (AMD HD7950) after hibernate

    Hello all,

    I have the following issue with my Z77 Extreme4 mainboard:
    If my PC hibernates for a while (1 day or more) my graphics card (Asus Radeon HD 7950 DirectCuII TOP) isn't recognized by the Bios or Windows.
    Changing the PCIe speed to Gen1 or the port it self doesn't help. The only thing that seems to help is to erase the CMOS multiple times and/or disconnecting the GPU.

    If the gpu is detected it is working fine...

    Is this a mainboard issue? All Bios versions are up to date:
    Asus HD7950: 113-C3810100-107
    ASrock Extreme4: P2.90

    Can anyone here help? Thanks. :)
