    BIOS screen doesn't load


    When I am afk for a longer time, the systems goes on standby. The screen is black.
    Generally I just press the power button and I am on the normal Windows screen from where I enter Windows.
    However today when I pressed the power button, nothing happened and the screen stayed black (when I set the screen on then off it displays "No signal".

    I shut down the power and restart.
    The fan works, the HD seems to do something (there are no beeps but then I think there never were before) but the BIOS screen never appears.
    Tried ctrl+alt+del, ctrl+alt+esc, del and f2 after power up but nothing happened.
    I did all this about 10 times but the result is always the same - black screen and no BIOS.

    My system is :
    Processor : I7 975
    MB : Asus P6T WS Professional
    Graphics : GeForce GTX 295

    What should I do ?

    @TomasV -

    Welcome to Windows Ten Forums!

    Remove the GTX with the power off and plug disconnected from the AC mains.

    Then plug in and power on using the on-board integrated graphics.
    See if that works, first. (POST screen and login.)

    If it does, then login and shutdown.
    Put the GTX back into the system - reseating the GTX card.

    Power on again and check for output.

    Do not enter the BIOS at this time.

    Please post back.

    Thanks.

    Thanks for the advice.
    However before I started attacking with a screwdriver, I tried one last time to press the power button.
    This time the BIOS loaded followed by W10 without problem so that I am in my system normally again.

    But that also means that I should have the possibility to access tools which could tell me what went wrong and most importantly what to do to avoid that it repeats.
    Can you advice me what to do and what to check to find out what the problem was ?

    This is a bit strange,

    I would reseat the GTX and try again.
    You can try looking into the Event Viewer but this is only if the machine actually booted in the dark.

    Keep your eye on it.

    HTH,

    seems to me your system went into "Hibernate" and pushing the power button did not wake it up, but rather shut it down..
    Thus a second push of the power button was required... I do not "Hibernate" my PC, I just let it go to "Sleep" and a wiggle of the mouse wakes it...

    Good point and easily correctable.

    Enable or Disable Hibernate in Windows 10

    Let's see. Thanks.

    As I wrote, I didn't press the power button only twice!

    I did it at least a DOZEN of times with no BIOS loading and only the black screen.
    But it is true, as I also wrote, when the computer is idle (I am afk) for a certain time it goes to "sleep" or "hibernation" (whatever the difference between these 2 terms is).
    That means that the screen goes black but the system stays under power (the power light is on).

    Normally the system "wakes" when I press the power button and gets me to the W10 loading screen.
    It was only today when the system seemed to "sleep" as usual and I pressed the power button as usual that nothing happened and the screen stayed black.
    Then I did the cycle shut off/start up about a dozen of times ALWAYS with the same result - black screen and no BIOS screen .

    Then, after the advice of Compumind, before starting to spend an hour with a screwdriver I tried one last time to start up and everything happened normally. BIOS screen came then W10 loaded as usual.
    So it seems to me that this problem has something to do with the "sleep" or "hibernation" when idle but I have no idea where or how to look it up.

    @TomasV -

    Reseating the GTX takes about 15 minutes, going slow.
    It's a suggestion, you don't have to do it if you are not comfortable.

    FWIW.

    Well after 2 days it happened again.
    This time it was not during the system's "sleep".
    Yesterday evening I shut down the system properly but this morning I have the same problem - black screen, BIOS screen doesn't load.

    I am ready to try Compumind suggestion but I don't understand it well.
    "Start up with integrated graphics" - I wasn't aware there were integrated graphics on my MB.
    But if there are, I'll have to connect the screen to something (now it is connected to the GTX), right ?
    How do I connect the screen to the "integrated graphics" ?

    Looking at the specifications for your CPU, it appears that it does not have integrated graphics after all. Too bad.

    Intel(R) Core™ i7-975 Processor Extreme Edition (8M Cache, 3.33 GHz, 6.40 GT/s Intel(R) QPI) Product Specifications

    So you might need another video card to test with or bring the system to a computer repair and let them do it for you.

    However, I would first suggest removing the GTX (with the power off) and blow out the slot with dust-off or similar, then reinsert it (lock it down) and test.
    (I would blow out the motherboard and fans, too, while you are at it.)
