    ASRock X99 Extreme4 boots only on cold boot

    Hello,

    The motherboard in question boots only on cold boot - if I cut power to the PSU it will boot fine, but as soon as I reboot from Windows or even short reset pins it goes into bootloop - 1 second on, a few off and so on.

    Initially the board arrived to me broken - bad PCH, after replacing it it worked for a while. I suspected a bad connection, but pushing the IC down does nothing. I don't really think that the PCH is dead, since it still boots and works fine until I reboot the PC. Obviously I tried looking for something that heats up or bad caps, but nothing so far.

    I tested the CPU, PSU and RAM in other boards, they work absolutely fine.

    Any ideas what else I can test?

    Check if the resistor under the network card chip has been knocked off. If so, it might have been accidentally knocked off during graphics card installation. Reinstalling it should fix the problem.
