    Minor problem switching on PC


    Sometimes when my husbands starts his pc from cold, it starts the process then before loading the OS it switches off again - or it appears to. Let me explain. What I've said does indeed happen but if he leaves it long enough perhaps 30-45 seconds it runs up no bother. It doesn't always do this either - only sometimes.

    In fact having just thought about what I've just written I'm wondering if its the new style BIOS looking to see what is installed since it does not show the mobo graphic a second time. If I'm right though, it does seem to spend a lot of time checking the make-up of the PC and I'm wondering whether anything may be dying, e.g. a hard drive for example.

    Its difficult to know what else to say about it as I just don't know what it could possibly be. What I will say is that his PC includes the following:

    Gigabyte GA-Z87-HD3 mobo
    RAM 16GB
    Processor i7-4770K
    Nine physical drives totalling 12.24TB six of which are internal, three external and includes at least two SSDs
    All drives are MBR except one, a 3TB drive which is GPT

    Does anyone have any comments? I should add that his PC has been behaving intermittently like this for some time and any help would be appreciated.

    You need to start eliminating things to see if you can isolate the cause. Start by disconnecting all external devices except mouse, keyboard and display. How does it boot from power off then. If better reconnect devices one at a time to see which is the cause.

    If not change, start disconnecting internal devices one at a time and test.

    That is the process I would follow to try to isolate the cause of the problem.

    Does he see the problem when doing a restart? If not then try turning off Fast Startup, see if that helps:

    That seems like BIOS/UEFI can't make it's mind which disk to BOOT from. I would go to BIOS settings and make sure that disk windows are installed on is first in line.
