    Hi! [​IMG]

    My specs are:
    CPU: AMD Phenom II X4 945, 4x 3000 MHz
    Mainboard: MSI 760GM-P23 (FX), Sc3+, AMD 760G Chipset
    RAM: 8192 MB DDR3-RAM
    HDD: 1000 GB, Seagate®/Western Digital®, SATA
    GPU: AMD R9 380
    PSU: COOLER MASTER G550M, 550 Watt, ATX 2.31

    Monitor: AOC e2243Fws
    OS: Win 10 64bit

    My problem:
    When I boot up my PC, it will do so normally until i get to the login screen. There the picture freezes and the monitor goes black, showing "no signal". The PC and fans run. Turning the monitor off an on or unplugging the hdmi cable and putting it in again won't help, so I have to shut down my PC by force.
    When I start the PC again, everything works fine. Even if I shut down the PC and boot up again after 1 hour or so, there is mo problem. If I wait several hours or to the next day though, the same happens again. Normal boot, loading screen, freeze, no signal.

    As GPU and PSU are new and the problem persists for several months, I started to think, if it could be my motherboard. I also thought of my RAM, but Memtest didn't show problems.
    So, is it possible that my motherboard is the problem?

    If yes, what can I do?

    Thanks in advance for your help! [​IMG]
