    Hi,

    When I boot my computer the BIOS doesn't display. First thing to show on the monitor is a fully booted desktop. Its been happening since around patch Tuesday but I think this is just coincidence.

    For now I can live with it but I can't boot into Linux (separate drive accessed from boot selector) and a planned HD upgrade has been delayed.

    The Mobo is an Asus P6X58D-E with a i7 930 @4.1Ghz. 6Gb ram, AMD 7950 Gfx, Boot SSD and a couple of mech drives.

    The system is water coold and has been stable for years.

    Any suggestions on getting back into the BIOS appreciated.

    have you tried hitting the setup key <DEL> or whatever? just keep hitting it for the 1st 15 seconds after turning it on... it will prob start beeping. then stop. see if it shows?

    Try using the del key on the num-pad ... apparently this helped some people before with an issue like this.

    While certainly odd if it just started... I have the same problem on 2 different systems also. On one, I need to have my display attached to a specific port on the gpu as it is the only one that will display bios. On another... it's silly uefi will only display on a monitor with a 1080 native res and I have a 1440.
    So, try other display output on the gpu, if none work perhaps try a different gpu? If that dosen't work either... maybe try flashing the bios as it may have a problem. Though... clearing the cmos could be risky. If the no display problem isn't resolved you will be stuck if you can't get past post from not being able to change a setting to boot like setting ahci or something.

    Can you get into the boot selection screen by pressing F10?
    You could try a different keyboard either.

    The boot selector is F8 (and that doesnt work), both Dels don't work and I have swapped the DVI cable around.

    Since the computer will boot into windows (I am typing on it now) I wan't to avoid resetting the BIOS (the order of drives is important since not everything that runs on start-up is on the SSD. and the SSD is not the default boot option when CMOS is cleared).

    I have thought about flashing a new BIOS but it is recommended to do this from within the BIOS on this mobo.

    Try doing a full shutdown - from a command prompt, type
    Code:
    shutdown /s /t 0
    this may give you a bit of extra time to get into the BIOS as it is different from the normal Windows 8 hybrid shutdown/reboot.

    Disconnect the hard disk. You should be able to look in the BIOS then and see what's going on.

    As IvanIvanovich said - the boot screen is on a different port, which has no display connected.

    If that doesn't work the bios on them boards can just be flashed from a flash drive, even if you can't access the bios. :clap:

    I had a similar issue in the past where my usb keyboard wouldn't turn on quick enough for the keys to work and it would pass by the delete key function. I found using an old non usb keyboard worked.

    I have 2 monitors.. 1 will immediately fires up and shows boot screen, the other is very slow and wont show till the bios is actually up.. as stated above, maybe a different port? vga cable?

    I'd assumed because it was an i7 motherboard that it wouldn't have PS/2 ports, but it does. Definitely try using a PS/2 keyboard like YEHBABY suggested - I've had problems in the past where the USB keyboard wasn't recognised by the BIOS.

    According to the manual, you need to press the Delete key to get into the BIOS.

    Its working now.

    Removing the gfx card, booting then re-inserting it and booting cleared it.

    A guess would be that the card/bios level drivers were failing and the card would only initialize when the windows drivers kicked in. It would explain why Del/F8 left a blank screen and windows safe mode wouldn't display.

    Thanks for you help guys, hope it doesn't happen again and I can put it down to random computer weirdness.
